Slam its vase to wake him up. Whenever Cractus leaves the screen, do not climb the ladders, otherwise it will move at the roof level and drop drool. Wait until it stays at lower height, and start to move forward. Watch out for the leaf hands, get to close range and stomp Cractus' head. Right after stomping, move away to dodge any drool drops. This drool will turn you into Zombie Wario, causing a time loss. In this case, a firefly will appear, and should be touched to remove Zombie status. When its life is low, it may move slower on the ground.
