Aerodent

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

Aerodent is a gray 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 - it must hit the soft patch in order for a successful hit, as if it is too close to the leg area, the hit will be unsuccessful and Wario must repeat this process again.

From this point, Wario must ram the padded legs (which will flash to show where to hit). After that, the teddy bear will flip, with Aerodent poking his head out of the inflated area. Wario must then ram Aerodent to damage it. If Wario's head hits the inflated bear balloon, it will go up a little. If Wario does not touch Aerodent for a while or the balloon rises high enough, Aerodent will inflate the balloon and go upward again.

Aerodent also takes a large amount of damage from the Large Lips.

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". Aerodent is the only boss that does not "die", as he simply gets knocked off the screen, while the other bosses are killed on-screen.

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 shop owner uses the Large Lips move on it, and Wario deals the finishing blow to it.
