Mistake

At times, when making a game, development members may make a mistake. Most of the time, these errors are detected by the quality assurance team, whose job is to play-test the game in search for such mistakes, so that they can be corrected. However, it's possible for some errors to go by undetected, or to not get fixed in time, meaning the final game is released with them still in it. For the most part, these aren't enough to affect gameplay or the game's story. In popular culture, they are also known as goofs. In the Pikmin series, there are cases of typos, grammatical errors, glitches, ways to go out of bounds, and inconsistencies.

For the sake of completion, debatable mistakes will be included on the article as well. Unless otherwise confirmed, every mistake listed here is speculative, and could in fact be purposefully made by the developers.

Leftovers

At points, leftovers from previous versions of a game may make their way into the final product in some form. This generates a minor inconsistency in the game mechanics, locations or objects, given that what's presented is different from what happens in the actual game.

Early enemy reel information

The Goolix on The Forest Navel.

Main article: Enemy reel discrepancies.

Some of the enemy reel's footage was recorded in an earlier – or at least different – version of Pikmin, as several of the objects cannot be found in those locations in the final game. One of the most noteworthy examples would be the Goolix appearing on The Forest Navel, despite never being encountered there during gameplay. In addition, the fact that all names are sorted alphabetically, besides the Swooping Snitchbug's, suggests the creature's name might have been intended to be different – possibly something beginning with "Flying". This error was not corrected in the New Play Control! port (which used the original GameCube footage), but was in the Switch port.

S.S. Dolphin credits mistake

An early model of the S.S. Dolphin (which can be found unused in the game files) can be seen projected on PNF-404 during the ending credits, as one of the Ionium Jets can be seen with a circular top instead of an hexagonal one, and the retracted egg-whisk-like propeller can be seen as a sphere. Both of these traits are found in the unused model, but not in the final game's ship.

Pellet carrying in the instruction manual

Main article: Pellet#Three Pikmin carrying a 1 pellet.

In the instruction manual, the page that describes the Onions and pellets contains an image of three Pikmin carrying a 1 pellet. In the actual game, this is not possible – only up to two Pikmin may carry a 1 pellet at the same time.

Bomb rock warning in the New Play Control! instruction manual

In the US instruction manual for New Play Control! Pikmin, the page that explains each Pikmin type's skills has two warnings about Yellow Pikmin and bomb-rocks. One of them states “Don't stand too close! If it stands idly when thrown, call back a bomb-carrying Pikmin to have it drop the bomb.” This is a leftover from the instruction manual of the original GameCube Pikmin game, and is no longer true in the New Play Control! and Nintendo Switch versions – the Pikmin keep their bomb rocks when called.

The Forest Navel geyser

The geyser at the south of The Forest Navel. It serves no real purpose.

At the south of The Forest Navel, there is a geyser on the platform where the Gravity Jumper can be found. This geyser merely shoots Olimar upward considerably high, and makes him land on the pond at the southwest. Because this does not aid the player in any way, and because there is a detailed path leading up specifically to the geyser, it is possible that this is the leftover of a previous version of the area, where that geyser actually had a purpose.

Olimar's movement

Due to errors in the vector math for the player movement, Olimar walks slower if the player tilts the analog stick in a diagonal direction. This is a common error in game development, and is usually a result of devs forgetting to normalize the player input. As such, it's faster to angle the camera such that the player has to tilt the analog stick in a cardinal direction in order to get Olimar where he needs. This oddity is not present in the New Play Control! version.

Written mistakes

• On the North American GameCube version's manual, in the page where Captain Olimar describes the game's plot, there is the typo “I then felt a premonition that my short trip would soon be become an epic adventure.”. "Be" is in one line, and "become" is in another, which could explain why this mistake was left undetected.
• On the Q&A section of the manual in the European GameCube version, there is a hint explaining how it is possible to slow down a Spotty Bulborb by holding onto its feet with Pikmin. "Holding" is spelled as "holdung", however; a trivial mistake to make on a QWERTY keyboard, given that the U and the I keys are next to one another.
• The back of the GameCube game's box, in the European version, contains a story summary with a typo in it: “Due to an unforeseeable collision with a meteor, I've crash-landed on a strange planet. My Ship is in pieces and my only hope for survival lies with odd creature I call Pikmin...”, given that "with odd creature" is incorrect. The US version's box instead states “I've crash-landed on a strange planet. My ship is in pieces—my only hope for survival lies with odd creatures I call Pikmin...”
• Andy Becraft was one of the engineers on Nintendo of America's debugging team, and is credited on Pikmin's credits sequence. In the New Play Control! version, however, his name is incorrectly written as "Beaucraft".
• When Blue Pikmin are discovered, Olimar describes the Blue Pikmin with phrasing that implies it has not entered water yet, describing it in such a way that implies that the newly-discovered Blue Pikmin could survive in water because it has gills, and using the phrase “There's only one way to find out...” as if the next option is to test its swimming abilities by putting it in water, even though the Pikmin is already standing in water for the entire cutscene.
• If the player opens the Blue Onion's menu and attempts to take out more Pikmin than the amount in the Onion, the message "There are no blues Pikmin to take out." appears. The correct message, "There are no blue Pikmin to take out.", has been added to the New Play Control version.
• The enemy reel entry for the Smoky Progg ends with a comma instead of a period.

Ship part function inconsistencies

Some ship parts are optional and mentioned to have no relation to the flight capabilities of the S.S. Dolphin, and therefore are not needed to complete the game. However, there are multiple parts that, evidently, have an unclear purpose or no relation to the S.S. Dolphin's flight capabilities (as inferable from Olimar's descriptions for these parts), yet are mandatory. Some examples include:

• The Analog Computer, which according to Olimar's description, only increases the emotional intelligence of the ship AI onboard the S.S. Dolphin.
• The Libra and the Sagittarius, both of which are gifts from his children and are never stated in his monologs for both parts to have any purpose.
• The Positron Generator, which can supposedly generate lots of energy. Olimar implies he uses this to heat up noodles, implying that it's not part of the spaceship's systems, and the Eternal Fuel Dynamo is said to have an unlimited energy supply, seemingly making this part redundant.
• The Pilot's Seat, which is just a seat cushion, although it is needed for the cockpit to be "back in order", according to Olimar.
• The Interstellar Radio, which going off of Olimar's description, is just a radio. Olimar specifically brings up in his second monolog for this part that not all parts are needed to fly the ship, hinting that the Interstellar Radio is not mandatory, even though it is.
• The Guard Satellite, which is only said to defend the S.S. Dolphin and is not said to do anything else in relation to the S.S. Dolphin's flight capabilities. This part does not do anything to defend the S.S. Dolphin in the opening cutscene from a meteor strike, and it's left unclear if the Guard Satellite is a weapon of its own or is reliant on the optional Nova Blaster being present to attack.

Other oversights

• When a ship part is collected and it's visible on the S.S. Dolphin, sparkles will collect to the spot where it is about to appear. When the Libra is collected, the sparkles collect to where the ship is standing, instead of where the Libra is actually located.
• Candypop Buds, geysers, and Iridescent Flint Beetles are internally considered bosses. Although this doesn't affect the game directly, it has the unintended side-effect of making the area's music change to the enemy variant whenever the player approaches a Candypop Bud or geyser.
• On the Fiery Blowhog's clip in the enemy reel, the camera's viewport can be seen clipping through the ground, revealing the black void below the map.
• In The Final Trial, there is a wall to the left of the landing site behind some plants with inconsistent collision; the collision extends further than the visual model.

Pikmin 2

Glitches

Carrying path oversights

See: Path oversights in Pikmin 2

General oversights

• When entering a cave or sublevel, the first leader to jump will always grunt like Olimar, and the second will always grunt like Louie. This is true regardless of the leaders that are actually on the party and the order at which they jump in, but if the second leader is fallen, only the first leader's grunt will play (still with Olimar's voice).
• The entries for the Ravenous Whiskerpillar and the Volatile Dweevil on the Piklopedia point out that the creatures have an associated Poko value of 1 and 0, respectively. These values provide no useful information to the player, given that Ravenous Whiskerpillars cannot appear underground, and Volatile Dweevils cannot be retrieved to the research pod. It is possible that they could at an earlier point in development, and that this value is a remnant of that time; other moot values, such as the Poko count of a Pellet Posy are displayed as "----", further confusing matters.
• Buried Armored Cannon Beetle Larvae cannot be stunned with Purple Pikmin, although the game files specify that the enemy should have the same stun properties as the free-walking counterpart, which can be stunned.
• If the first Pikmin to drink nectar in a playthrough is a Bulbmin, the cutscene will play, but the sound of a regular Pikmin will be heard, instead of a Bulbmin sound.
• The tenth sublevel in the Cavern of Chaos becomes darker if the player has the Solar System as opposed to lighter. An explanation for it can be found here.
• Recovering an enemy corpse by the ship's pod for the first time will activate the cutscene that corresponds with it. For garden-themed sublevels, this causes the camera to accidentally pan up to view the black space above the skybox.

Dialog inconsistencies

• When the Justice Alloy is collected, the Hocotate ship claims that getting bitten or stepped on will produce less pain. This is a huge simplification of the damage reduction benefit, as all damage suffered is reduced, not just from those two sources.
• The game does not distinguish between leaving a cave and starting a new day for the purpose of some cutscenes. So some dialog that makes sense at the start of a new day won't make sense when exiting a cave.
  • If the player loses all Pikmin of one type inside a cave and goes to the surface, the ship will state that there was a Pikmin extinction "yesterday".
  • If on the day the player obtains Purple Pikmin, they leave some Purple Pikmin behind before entering the Emergence Cave again, the ship will explain how the Pikmin have been stored in its hull, but greet the leaders with "Good morning!"
• Olimar's journal on The Key has him describe the Beady Long Legs as a "Pikmin-devouring spider", despite the fact that the Beady Long Legs is one of the few enemies that does not eat Pikmin in any way; it only crushes them. This mistake is not present in the Japanese script.
  • Additionally, in Olimar's notes for the Beady Long Legs, he specifically mentions that the Beady Long Legs is not, in fact, a spider at all. This makes both parts of this description inaccurate.
• In the journal entry for the Universal Com, Olimar talks about how the ship and Louie are calling him out for being wrong about what the treasure is. This treasure is found on sublevel 12 of the Dream Den, before Louie can be rescued on the final floor, making it possible to read this journal entry before Louie could possibly have commented on it. This mistake is not present in the Japanese script, which does not specifically mention Louie and the ship by name.
• The Talisman of Life contains multiple Luck Wafers as claimed in the Sales Pitch, but the Luck Wafer is worth 140 Pokos while the Talisman of Life is worth just 90 Pokos. This mistake is not present in the Japanese script, where they are simply referred to as "cards".
• Louie's notes on some enemies make references to bodies or body parts that Louie couldn't possibly have collected for cooking, due to the fact that they are shown to disappear upon death, in-game. A full list can be found here.
• If the end of day explanation has not been heard by the player until after the debt has been repaid, the Hocotate Ship will still address Louie, even though he is not present.
• If the player discovers the Amplified Amplifier, even if the Ranging Bloyster is defeated when petrified, the ship will still state "The gooey creature dissolved, leaving this curious item behind."
• Several lines do not take into account if a leader is down or not.
  • If the player discovers the Five-man Napsack, even if Olimar is down, the ship will state "Well done, Captain Olimar!"
  • Several tutorial dialogs will still address Louie, even if he is not present. The same will also apply to Olimar if he is knocked out.
  • Discovering the White Flower Garden will have the ship state "The exploration pod will drop its loot to make room to carry you, Louie, and the Pikmin to safety.” even if one of them is knocked out. If Louie discovers the cave, the ship will still address him as if he was Olimar instead.
  • When discovering the Glutton's Kitchen, the ship will state "You are both drooling...” regardless if a leader is down.
  • When discovering the Shower Room, the ship will state "I have been observing the two of you working together. You have been cooperating well." regardless if a leader is down.
  • When discovering the Submerged Castle, the ship will state "You two must go alone.", even if a leader is down.
  • Dialog for discovering the Hole of Heroes will still address The President and Olimar directly even if one has been knocked out.
• In the European Wii version, when discovering the Emergence Cave, the ship will erroneously state "Separated Pikmin will head to the Onion." twice.
• When collecting The Key, the dialog will still mention "Challenge Mode can now be accessed from the title screen.", even if Challenge Mode is already unlocked.

Visual mistakes

• Olimar's journal on the Aquatic Mine has him explain the changes to the Perplexing Pool and other areas being caused by frequent tectonic shifts. However, this hand-wave would only explain how The Impact Site and The Final Trial are close enough in this game to be combined into the Wistful Wild. The artificial elements seen in some of the areas, some of which is explicitly buried into the level and patterned out like in the Awakening Wood, cannot be caused by tectonic shifting and is left unexplained.
• On the title screen's "Summer" theme, Dweevils can be seen running around the tree trunk. These dweevils are given an incorrect texture, the same texture as the Ravenous Whiskerpillar who also appear on the tree trunk.
• On the cutscene that plays when the player clears the debt, the Hocotate ship announces the return to Hocotate and the camera shifts to the sky, where a faint image of the President is seen. This image was likely cropped from an image with a white background, as it becomes clear that the area of the image between the President's curly hair was not cropped out: it remains white. This was fixed in the Nintendo Switch port.
• The texture for the Geographic Projection is flipped horizontally. If one flips the treasure upright, Africa will be to the left of South America, which will be to the left of Europe, contrary to the real world. Whether this is a mistake or not is not known, since it could've been flipped on purpose to represent continents in a familiar manner to most people, considering that the treasure is only ever found upside-down.
• The cave unit that is a zigzagging metal platform with multiple corridors has no underside for the highest platform and a missing polygon on one of the beams that holds up the stage. This lack of an underside can be seen if the player changes the camera's mode to ground level view and stands at two of the low points in the stage. The easiest way to see this mistake is to enter the first layout of Rusty Gulch, as that layout contains that cave unit.
• There is no counter for Bulbmin in the cave selection screen in Challenge Mode. As a result, a player may expect that they will receive no Pikmin at all for Hidden Garden, when they actually get two Bulbmin. There is an empty space to the right of the Purple Pikmin counter, so it's possible that there could've been one intended to be there.
• Depending on the regional version and area, the Decorative Goo in the Treasure Hoard can appear to float or have no shadow, as explained here.
• In the Awakening Wood, there's a large branch far out of bounds to the east of the Blue Onion sticking out of the ground. This branch is missing triangles on the bottom, making it look like it's floating in the air from some angles. By going to the Bulblax Kingdom's plot and switching the camera to ground level view to look at the branch, the player can see this mistake more clearly.
  • The other, smaller branch placed between the Blue Onion and the White Flower Garden is also floating off the ground, but it's much harder to notice, and can be seen from the electric gate near the Blue Onion.
• The textures used for the sides of the concrete blocks in the Valley of Repose wobble in sync with the area's shadows. This is caused by the animation data for the texture being set to adopt the movement pattern intended for the areas' shadows due to the value that determines how the texture is supposed to move being mistakenly being one digit higher than it was supposed to. This mistake is also present on the Piklopedia variation of the stage.
• In the European Wii version at 60 Hz, there is a persistent glitched line at the bottom of the screen caused by misconfigured rendering settings. This was likely unnoticed due to the line being hidden by the television overscan, which was usually enabled at the time.

• 

  The white background of the President's image was mistakenly left between his hair's curl.
•

Written mistakes

Typos

• It is possible to tell that the treasures exclusive to the European version of Pikmin 2 received less quality control, as quite a few typos managed to make their way into their English descriptions. This was not intended, as proven by the fact that most of the descriptions in the New Play Control! Pikmin 2 variants have been fixed. A list of these typos can be found on this category. There are some typos present on treasures available in all versions as well; oddly, the US Wii version shares many of these and contains a new low-quality description of its own, in the form of Olimar's journal entry for the Patience Tester.
• Unlike all other treasures in Pikmin 2, the Empty Space Container does not have its name in title case in the GameCube version.
• Olimar's journal entry for the Fleeting Art Form in the European GameCube and US Wii versions of the game has the text "out.The", without a space between "out" and "The".
• Olimar's journal entry for the Lustrous Element in the European GameCube version calls Hocotate "Hokotate" twice.
• Olimar's journal entry for the Divine Cooking Tool calls Hocotate "Hocatate" in the GameCube version. This was corrected for the Wii release.
• Olimar's journal entry for the Vorpal Platter writes "could effortlessly sheer through the armor plating" in all versions until the Wii European release, which uses the correct word "shear".
• Olimar's journal for the Memorable Gyro Block has the word "accidentally" misspelled as "accidently". This was fixed in the Nintendo Switch versions.
• Olimar's journal entry for the Flare Cannon calls the Titan Dweevil "monsterous". The correct spelling of the word is "monstrous".
• Olimar's notes on the Orange Bulborb say "with deep orange body" in all versions but the Wii European release, which writes "with a deep orange body" instead.
  • Strangely, in Pikmin 3 Deluxe's Piklopedia, this typo is still present in all versions, including the European release. It is fixed in all versions of Pikmin 4.
• The Dwarf Red Bulborb's scientific name is Pansarus pseudoculii russus, with one 'o' in the species name, prior to the European release of New Play Control! Pikmin 2. Since all other breadbug mimics use two 'o's, this spelling is presumably a typo. The European version of New Play Control! Pikmin 2 corrects this.
• Olimar's notes on the Glowstem have the misspelling "resemblence", except in the European Wii version, which uses the correct spelling of "resemblance".
• The "Results Prior to Repaying Debt" screen on the North American and European GameCube versions says "Results Prior to Repaying Dept". The files for this menu lack a texture for a lowercase "b" entirely, which hints at the menu data having been generated without the "b" being in the string in the first place, making this a simple typo. The Wii North American re-release has corrected the typo, and the European Wii version of Pikmin 2 says "Results up to Debt Repayment" instead.

Incorrect information

• One of the advisories for 2-Player Battle says that the player can hold up to four roulette spins. This is technically correct, but misleading, as the player can actually store five powers – the four queued spins plus the current power on standby.
• The rules for 2-Player Battle say, for the boulder item, "Boulders drop on opponent", which is correct. However, the European version of New Play Control! Pikmin 2 states "Boulder drops on opponent", knocking down the number of boulders to one. In-game, several boulders fall down, not just one.
• In the English version of the Piklopedia, the Doodlebug belongs to the "flint bug family", however in other language versions it belongs to the flint beetle family. This was fixed in the Nintendo Switch port.
• In the Canadian French version of Olimar's journal for the Five-man Napsack in New Play Control! Pikmin 2, it says the player must use to lie down instead of . This mistake only exists on this exact version of the journal.
• In the French version of New Play Control! Pikmin 2, the pause menu incorrectly calls the Sphere Chart "Système Solaire", which is the name used for the Solar System. This does not happen in the ship's dialogs.
• In the Hocotate ship's dialog when the player collects the Brute Knuckles, the ship calls the upgrade "Rocket Punch" instead of "Rocket Fist". This mistake is only present in the US GameCube version.
• Olimar's notes on the Cupid's Grenade in the GameCube and US Wii versions of Pikmin 2 describe the treasure as if it were a plant that grows two types of berries, despite it being a singular cherry. This is a translation mistake, as the Japanese version correctly notes that it's a product from a tree that could be either of two varieties. The European Wii version describes it as having two different flavors to remove the mistake, and the Nintendo Switch release properly translates it as coming from a tree.
• In the Japanese version of Pikmin 2, the Titan Dweevil is repeatedly described as having swallowed or absorbed the treasures in the Titan Dweevil Series, possibly describing an earlier iteration of the fight. Most of these mentions were removed in the English translation.

Missing sublevel objects

Due to the way sublevel generation works, it is possible for some important objects that are usually meant to appear to not show up at all. The following tables list known cases, along with the probabilities of that happening.

For cases in these lists where the treasure is inside of an enemy, what happens is that that enemy does not appear.
