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. It only appears in The Curious Factory and Hotel Horror, and only three appear in the whole game. If Wario goes near it, the Kaentsubo will flip and create a flame on the ground. If Wario touches the flame, he will turn into Flaming Wario.
