Cractus is the second boss in the Game Boy Advance video game Wario Land 4. Cractus is also the guardian of the Emerald Passage. This strange monster resembles a giant, drooling cactus. If Wario touches Cractus' drool, the portly anti-hero will turn into a zombie. To defeat Cractus, Wario had to slam into the monster's head from above.
