Good animation and sums up the cartoon pretty good. I've actually found myself enjoying Tuff Puppy, but I really hope the main charecter matures SOMEWHERE down the line.
If I recall, it was made by the same who made Fairly Odd Parents and Danny Phantom though, and seeing how that studio has had more hits then misses, I'm not surprised it's one of Nick's better newer cartoons.
Can't wait for the Total Drama Revenge of the Island!
