Armored Cannon Larva
Armored Cannon Larvae (フタクチドックリ?, lit.: "Tokkuri Top-Mouth"; Armored Cannon Beetle Larva in Pikmin 2; Armoured Cannon Larva in the European version of Pikmin 3) are enemies in Pikmin 2 and Pikmin 3. They resemble large larvae with some of the similar Armored Cannon Beetle eyes and mouth. They act the same as the Armored Cannon Beetle, but turn and spit at a faster rate and have much less health. Their boulders roll in a straight line in Pikmin 2, but follow the terrain's curvature in Pikmin 3. They come in two types: one that walks around and one that burrows out of the ground; only the burrowing form is found in Pikmin 3. A related species called Decorated Cannon Beetles exists in larval form, in Pikmin 2, but the adults are not seen in any game so far.
Like the adult Cannon Beetles, they have a blowhole on the top of their head, but it is either non-functional or not as powerful, so Pikmin cannot become stuck in it like with the fully grown beetles. Because Cannon Beetle Larvae lack the thick exoskeletal armor characteristic of the adult beetles, these enemies are vulnerable all over their body, but can buck the Pikmin off when attacked. They can be manipulated into destroying other creatures by making them spit boulders at a leader when they are beside an enemy. Moving out of the way before the rock hits them, the rock will hit the enemy that was behind.
In Pikmin 2, the rocks that are shot out cannot be petrified, but they can, however, be destroyed if a Purple Pikmin is thrown on them. In addition, leaders can withstand a rock collision without suffering damage or knockback by lying down.
At times, Armored Cannon Larvae might appear buried in the ground, instead of free-roaming. They will never unearth more than half of their body, and will not move from their spot.
In Pikmin 2, a buried larva is internally recognized as a different enemy from the "normal" one. It has a lot more health than the walking counterpart. Due to what appears to be oversights, this buried version cannot be stunned by Purple Pikmin, and defeating it will not work for unlocking the Armored Cannon Larva entry on the Piklopedia. The game files indicate that the buried version has the same stun time and stun chance as the roaming one, so it is unknown why they cannot be stunned.
The Armored Cannon Larva is a relatively stocky and slow creature. It wanders around aimlessly until confronted by a leader or a Pikmin, at which point it will take aim and fire a large boulder from its mouth. Though fast-moving, this boulder moves in a straight line, unlike those spat by the Decorated Cannon Beetle. The rocks crush any Pikmin caught underneath them and deal great damage to other enemies. When attacked, the creature will buck all Pikmin off with a very similar motion to the Fiery and Watery Blowhogs.
Occasionally the Armored Cannon Larva is found buried in the ground, in which case it will halfway emerge when approached. Though this variation will not move, its attacks are identical to its walking counterpart. Additionally, it is sturdier, being unable to be stunned by Purple Pikmin and having significantly more health.
The Armored Cannon Larva is very similar to its appearance in Pikmin 2. Notably, it now only appears in the ground, and its boulders are unable to crush Rock Pikmin, and strangely, Winged Pikmin.
If enough Pikmin are available, swarm it and it should die before it can harm any Pikmin. If there aren't enough to do this or there are other factors that make this strategy ineffective, throw Pikmin onto it, preferably from behind. If the beetle bucks, call the Pikmin back as quickly as possible, repeat this process until the creature is defeated. If the larva is able to spit a rock, once it begins the animation, round up all the Pikmin you can and guide them out of the boulder's path using the swarm maneuver. Another strategy is to throw Purple Pikmin on it, stunning it. It is a more effective strategy, but if no Purple Pikmin are available and/or if they shouldn't be risked, the first strategy is recommended.
Alternatively, if you are placing a high priority on Pikmin life, then you can just use the leaders to deal with the creature. Punch it until it begins its bucking animation, then back away for a second, and return to attack. This may take a while but you will eventually defeat the creature by repeating this process. If two larvae are present in the same area, you can defeat them in a much more timely fashion by drawing one's aim over to the other, and having the rocks they spit do the killing.
Approaching the creature with Rock Pikmin will work best, as they are immune to its crushing boulders. When it emerges, throw the Rocks quickly onto it. 20 direct hits will kill the creature. If no Rock Pikmin are available, then use a large army of preferably Red Pikmin to defeat the Cannon Beetle in a very short time by charging at it just after it emerges from the ground. If executed properly, the creature won't be able to attack even once. Note that Winged Pikmin are also immune to its boulders, in that they get knocked back instead of killed, making them effective at killing the creature.
“This specimen is a lithopod larva. This expedition was unable to confirm the existence of any mature lithopods, leading to concerns that the species was extinct on this planet, but the discovery of the creature in larval form eased such concerns. Lithopods, like flint beetles, use internal metabacteria to aid chemical digestion. These metabacteria can only survive in certain environments, such as within the body of certain insects, so lithopod larvae do not contain any metabacteria immediately after hatching. Larvae feed on partially digested ore regurgitated by mature lithopods, ensuring the larvae obtain metabacteria they would not normally have acquired.”
“Carefully remove every grain of sand, peel back the exoskeleton, and slurp heartily!”

“Slow but mighty, Armored Cannon Beetle Larvae can make a good day into a bad one with one roll of a boulder. When one of the creatures sends a rock attack your way, use the C stick to have your Pikmin move out of the boulder's path as a tight unit, then throw soldiers onto the creature's back.”
Pikmin 3 Prima Guide
“The Armored Cannon Larva is another large, burrowing creature. Like the Arctic Cannon Larva, this creature attacks by firing projectiles at its enemies. Unlike the Snowballs utilized by its counterpart, however, the Armored Cannon Larva's projectiles are capable of crushing most Pikmin. The Armored Cannon Larva's projectiles cannot damage Rock Pikmin, but they will incapacitate them for a short time. When you attack one of these enemies, do so with a fairly large squad of Rock Pikmin. Flank the creature, then attack by throwing each of your Rock Pikmin for maximum damage.”
The creature's initial name, Armored Cannon Beetle Larva, is because of the fact that it is a larva of the Armored Cannon Beetle. That is the name the enemy has in the US and European regions of both Pikmin 2 and New Play Control! Pikmin 2. For Pikmin 3, the "Beetle" part was removed, and in addition, because of spelling, the word "Armored" became "Armoured" in the European version of the game. In Japan, they are called フタクチドックリ?, which is the same as the Armored Cannon Beetle's Japanese name.
Their scientific name, Granitus chukkulinae, is the same as the Armored Cannon Beetle's scientific name. Internally, the free-roaming Armored Cannon Larva is identified as
