Normal sullvan is an supporting character of the show. He is the normal verson of Sullvan Dog.
He looks exaclly like Sullvan. After all he is. However, instead he dosen't have hands or arms. His hands and arms are replaced by another pair of legs that look just like his other legs. Instead of barking, he chatters, however, in,The Super Wattersons 2, he barks and growls at The Wattersons.
Since he chatters and has four legs and he can become someone that can both be an dog or a person that has 2 legs, He resembles Perry from Phineas and Ferb.
He is 2# in The Gumball Character Challange
He is noted as the cutest character in the show as said from some commeents on YouTube.
