Kaentsubo

Kaentsubo (火炎壷 or 火炎ツボ, meaning "flame jar") is an enemy in the Game Boy Advance game Wario Land 4. It is a creature with the appearance of a living torch that has a blazing flame in its body, and it only appears in the Ruby Passage and the Sapphire Passage. If Wario goes near it, the Kaentsubo will flip and create a flame on the ground. If Wario is to make contact with the flame, he will turn into Flaming Wario. Only three appear in the whole game.
