How to: Position Oatchi on the opposite side of a short wall and leave him idling there. Position the leader on the opposite side of the wall. When the prompt to ride Oatchi appears, press the button. The leader should perform a jump in Oatchi's direction to get on him, but if the wall is low enough they will jump on top of the wall instead.
Effects: Allows a collected Wayward Moon to respawn, making it possible to earn more Sparklium from it and increase the completion tracker over 100%.
Prerequisites: Have access to Cavern for a King and have collected the Wayward Moon on sublevel 10 of the cave.
How to: On sublevel 10 of Cavern for a King, allow the Smoky Progg to hatch, wait one minute, then use Rewind Time to go back to after the boss was activated. It will once again be carrying the Wayward Moon, and will drop it when defeated.
Notes: Increasing the completion tracker over 100% with this glitch will also trigger completion-related cutscenes. The Treasure Catalog will count the extras in the "Found/Total" field, but there will be no extras in the diorama for the Spring Crop Series.
Effects: Allows you to escape the intended play area.
Prerequisites: Be able to ride Oatchi.
How to: By standing on the very edge of a ledge while riding Oatchi, he will tilt as if he is standing on a sloped surface. By aiming up the incline and using rush, Oatchi will launch a distance into the air as he runs forwards. This can clear some otherwise impassable walls.
Effects: Allows you to clone Pikmin, as well as go over the 100 Pikmin limit.
Prerequisites: Be in a cave sublevel with a Candypop Bud in it, and have Pikmin of that same type.
How to: Throw 5 Pikmin of the Candypop Bud's type into it. It will spit out the 5 seeds back and open up again to allow more Pikmin. During this opening sequence, throw more Pikmin at it. Eventually, some of them will be considered inside the Candypop Bud and ready for conversion, while in reality they actually slid off the flower and are in the sublevel with you. As a result, when the Candypop Bud spits out more seeds, it will include some extras because of the Pikmin it thinks it managed to take in. By repeating this over and over, the extras will eventually pile up and can break the Pikmin limit. This glitch is easiest to perform with Purple Pikmin.
Notes: Only 120 Pikmin will follow you/hop on Oatchi at a time. While performing the glitch the inverse can also happen, in that Pikmin that successfully went inside the Candypop Bud won't be accounted for, meaning you can lose Pikmin if your timing is off.
Prerequisites: Have unlocked the type of Onion that you want the type of Pikmin to be duplicated, have saved Dalmo, Schnauz, or Puddle, is in the Rescue Command Post, and have not collected all pellets in the area.
How to: Open a cave menu but do not enter the cave. Talk to Dalmo, Schnauz, or Puddle to unload the area and go back afterward. Finally, bring a pellet to the Onion. The Onion will produce 4 seeds for each pellet if done correctly.
Notes: The types of Pikmin with the sprouts will not be produced if not put into the Onion. If you haven't unlocked the Purple Onion yet, you can take out 100 Purple Pikmin and wait. This trick can also be used to get infinite raw materials by talking to François.
Effects: Makes Winged Pikmin fly off without stopping. Also randomly makes a crystal nodule break for no reason.
Prerequisites: None.
How to: Throw or charge a few Winged Pikmin at a crystal nodule. If you use too many, the crystal might break by itself. Some of the Pikmin will hover above the obstacle, and some will fly off in whatever direction they were moving at a random moment. When the crystal breaks, those Pikmin will return to being idle like normal, but they may be too far out of bounds to be easily accessed.
How to: Let Oatchi carry an object, like an enemy corpse, and then get hit by an Arctic Cannon Beetle's snowball just as he's spitting it out. The animation will be interrupted and the object will stay at a small size.
Notes: None.
Possible explanation: None.
Minor
Gameplay
Oatchi can rush against something to make nearby Pikmin sprouts pop out of the ground. However, if he rushes against a Candypop Bud right after it ejects seeds, the seeds will be "plucked" in mid-air.
Rarely, Pikmin can get in odd positions while trying to carry something, and may need a few seconds before they start moving. After a while they'll instantly snap into the right orientation and position.[1]
It is possible for a Glow Pikmin to go partially underground when ordered to charge. The Pikmin will pop out when the player gets near.[2]
Aesthetic
By going to the Piklopedia, selecting an enemy that is active at night, leaving the Piklopedia, then going to the Treasure Catalog, the treasures will be displayed at night. Pressing to toggle to day will reload the scene and show night still. Pressing again will change to day as expected, however.
If the player highlights any treasure of the Ultra-Hyper-Technology Series in the Piklopedia and swaps to the page that shows where it was first seen and what series it belongs to, the series name is large enough to overlap with the "Series:" label.
The tracks of the music that plays in the Treasure Catalog sometimes desync.[3]
