Aerodent

Aerodent is a rodent that appears in the video game Wario Land 4 for the Game Boy Advance.

Description
Aerodent is a rodent that rides atop an inflated bear balloon, which can shoot fireballs, and guards World 3 of the Golden Pyramid. While it deflates when hit with a sharp object, Aerodent will then begin to reinflate the balloon, leaving him exposed to damage. He has three treasure chests for Wario to acquire, although they must be acquired in a certain amount of time, and will go to the Golden Diva's lair in the Golden Pyramid. He also guards a piece of jewelry used to gain access to the Golden Pyramid.
