Swiggler

Swiggler is a large, Shroob-created, bio-mechanical Wiggler that was vital to the Shroob's conquest of the Mushroom Kingdom. Swiggler had the unique ability to transform the vim sucked from Toads into a fuel source for the Shroob's flying saucers. The giant Wiggler resided in a special room in the Vim Factory. In his lair, Swiggler would drink vim and, using special chemicals inside its body, transform the vim into fuel. Shroob UFOs would than attach themselves to Swiggler with special conducts, powering up the flying saucers.
