Yellow Wollywog

The Yellow Wollywog is probably the first thing that comes to mind when one hears the term 'amphituber' or 'wollywog.' These frog-like creatures can usually be found in or around large, open-air bodies of water. They are known to leap into the air with the intent of landing on and crushing small Pikmin below, and behavior which is most readily explained as an attempt to drive predators away from developing eggs. They are yellow version of the wollywog with a green forehead.

Olimar's Notes
This magnificent specimen has the brightest gold coloration and the greatest number of lateral spots of any member in the amphituber family. The species seems to have lost some swimming proficiency with the evolutionary adaptation that granted it greater jumping ability. The amphituber inhabits aquatic shallows and shows an instinctive drive to jump upon and squash smaller creatures.

Louie's Notes
Beer-batter and deep-fry for a down-home flavor you won't soon forget!

Pikmin 1
These dangerous enemies must be dealt with carefully, as one false step could mean the loss of dozens of Pikmin with a single attack. Swarm with as many Pikmin as are on-hand and they should be able to weigh the Wollywog down to the point where it cannot jump; as their health dwindles, Wollywogs can often summon the energy to make a last-ditch leap into the air, so be prepared to call your Pikmin back when its HP meter enters the red zone. Any Pikmin hanging onto the Wollywog when it lands will be thrown off and possibly deflowered from the force of the impact, sometimes spelling doom for non-blue Pikmin if they are knocked into a nearby pool.

Pikmin 2
Wollywogs are much harder to ground in Pikmin 2, even if numerous Pikmin are thrown onto its back, but swarming can still be an effective strategy, as the radius within which the Wollywog can crush a Pikmin is substantially smaller than in the first game. Purple Pikmin will also work exceedingly well when thrown at this beast in large numbers, as each one carries the chance of stunning it, preventing it from fighting back. Even so, often the safety strategy is simply to punch it with your captain, especially if the Rocket Fist upgrade is available.

Pikmin:Redemption
In PR these are actually found on the first sublevel of some caves as well as above ground. Not much else can be said about them.

PikSpore
PS undefined They are identical to their Pikmin 2 counterparts. If you fight them on a cave with bottomless voids, you can easily kill them by making them jump into the void.

trivia
Chuggaaconroy says that these are these serial killers of pikmin.
