Amphibigun is an enemy that appears in the game Wario: Master of Disguise. They are only encountered in the Allergia Gardens during Wario's adventure there. They are green creatures that are attached to walls and shoot bullets at Wario. The bullets move very slowly and can easily be avoided. Any attack can be used to take out these creatures.
The small critter was designed to attack in the same way a frog catches prey with its tongue. Which is a pretty bad way to go.
