Cractus

Cractus is the second boss in the Game Boy Advance game Wario Land 4. Cractus is also the guardian of the Emerald Passage. This strange monster resembles a giant, drooling venus fly trap. 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; by touching the firefly, its light will return Wario to his normal state. To defeat Cractus, Wario had to use the vines along the wall and slam into the monster's head from above.

In addition to the drool, Cractus can also attack by jabbing Wario with its cactus-like arms. Also, mere contact with the boss's toothed, gaping mouth will cause damage.

Cractus also appears in one of the ending scenes, chasing Wario.
