Cractus

Cractus is the second boss in the Game Boy Advance game Wario Land 4. Cractus is also the guardian of the Emerald Passage. It is a large, drooling Venus Flytrap with leaf-like appendages. If Wario touches Cractus' drool, the portly anti-hero will turn into Zombie Wario, wasting precious time. He can't attack Cractus while in this form. A firefly will fly by if this happens; touching will return Wario to his normal state. Cractus can also attack by jabbing at Wario with its arms, and mere contact with the boss's toothed, gaping mouth will cause damage. To defeat Cractus, Wario has to use the vines along the wall and slam into the monster's head from above. Aside from the Emerald Passage, Cractus appears in one of the ending sequences, chasing Wario through the forest.
