The Scourge of Sub-Con
Wart is the main villain of Super Mario Bros 2
. In an attempt to conquer Sub-Con
he built a Nightmare Machine which filled the world with monsters. When the player fights Wart in his castle, he stands on a high platform and spits streams of bubbles from his mouth, while a machine in the center of the room randomly throws vegetables around. Wart is allergic to vegetables, and can only be defeated after enough of them are thrown into his mouth.
