In Pikmin: Clouded Skies
The Croggywog is a very dangerous and unstable member of the amphituber family appearing in Pikmin: Clouded Skies. Unique from other amphitubers, the Croggywog has a bladder-like organ that produces a volatile liquid used for self-defense. The Croggywog secretes this fluid through pores on its skin, and when the creature lands after jumping, a cloud of fire appears around it and the ground surrounding it is set ablaze. The chemical can ignite virtually any surface, but fires created by it are quickly extinguished by water. When exposed to fire other than its own, the Croggywog will violently explode, destroying everything around it and sending fiery shrapnel flying in all directions. The creature can be killed by Pikmin or leaders as easily as other wollywogs are, but Red Pikmin are recommended to fight it with.
