Creepie's younger brother, Gnat, is a wild and crazy Wolf-bug. He's big on excitement and short on chit-chat. Gnat mumbles and garbles then shouts out one or two words, but Creepie always knows exactly what he's saying. He's an "Extreme Bug," who gets a rush out of trying to avoid the human hand, the fly swatter, or the Giant Foot. He regularly hitches a ride to school in Creepie's backpack, and once he's out, he's always buzzing around Creepie and getting them both in trouble.
