Barfatronic Lavachomper

The Barfatronic Lavachomper is a large head that controls lava flow from Wario: Master of Disguise. It appears as the boss of Sweatmore Peak, where Wario must fight it in order to pass.

To defeat it, Wario must first become Captain Wario and fire torpedoes at three pillars on the floor near the Barfatronic Lavachomper. While doing this, its eye will open up and fire small balls of energy to defend itself. After this, a hand will appear from its mouth and pull a switch, dropping bombs similar to Count Cannoli's. Wario must then become Genius Wario and send one of the bombs flying towards the Barfatronic Lavachomper's eye using the punching glove. This will cause it to release a toilet from its mouth. If Wario becomes Arty Wario and purposely messes up to draw poop above the toilet, it will run to the right and hit the Barfatronic Lavachomper's uvula. This will cause the toilet to go back inside and a heart-like device to come out. Thief Wario must tackle this heart until it breaks. This damages the Barfatronic Lavachomper, causing it to refill the arena with lava and respawn the three pillars.

When this process is repeated two more times, the boss will explode and be defeated. Afterwards, Wario can advance to the Blowhole Castle.

In-game description
''A device built to regulate the flow of magma, and also seek out and terrorize the occasional intruder. Why it is so darn weird is anyone's guess.''
