Aerodent

Aerodent is the fourth boss in the Game Boy Advance game Wario Land 4. He guards the Topaz Passage.

Aerodent is a grey mouse ghost that hides inside an inflated bear balloon. When fully inflated, this balloon is out of Wario's reach. From this safe vantage, Aerodent drops Pin Enemies in an attempt to harm Wario. Wario can stun these enemies by jumping on their heads, flipping it upside down so its pin is pointing upwards. Throwing the enemy up at the bottom of the teddy bear will deflate it, forcing Aerodent to desperately reinflate it. If Wario can deliver a leaping charge on one of its feet, it will rotate upside-down and expose Aerodent himself to attack. Wario can strike the mouse monster several times before it eventually rectifies its bear balloon, and the process repeats.

Once Aerodent withstands enough damage, it begins to throw flaming sticks at Wario, setting the ground alight on contact. Wario will turn into Flaming Wario should he be burned, losing all control and wasting valuable time. After enough hits, Aerodent is defeated and Wario is rewarded with the creature's Necklace.

His name is a portmanteau of "aero", describing his airborne status, and "rodent".

Super Mario-Kun
Aerodent appears also as a boss in volume 28 of Super Mario-Kun in the Wario Land 4 arc. It can shoot fire at Wario, transforming Wario into Flaming Wario. It takes heavy damage when the Item Shopkeeper uses the Large Lips move on it, and Wario deals the finishing blow to it.
