Benny is a rather short and chubby cat with blue fur, and a cream colored muzzle that takes up most of his face, unlike the rest of the gang. His tail is short and stubby, almost triangular at times, almost like that of a young kitten's tail. He usually wears a white cardigan, buttoned at the top with a single button. Unlike the other cats, his eyes are portrayed as small little dots.
Benny may appear to be simple-minded, but he manages to ask the most logical questions during the gang's erratic endeavors. He is often times naive, innocent and slow, but not stupid. The bond between Benny and TC is based on a sincere, devoted friendship between them. Benny has a tendency to complain that hes hungry at inappropriate times. He also appears to be something of a mama's boy.
- Benny claims that he and TC met in the Boy Scouts in The Unscratchables.
- Benny is modeled after his voice actor, Maurice Gosfield.
