Remember television's first CG show Reboot?
I recall a second season episode that made references to classic cartoons by having a character named Rocky: The Rabid/Rapid Raccoon go against Enzo.
Looks like the writers and animators had fun doing the wacky gags, but it really looks weird in a CG setting.
If you're interested, follow the links to view the episode in 3 parts:
Rocky Raccoon doesn't show up until part 2, but I hate posting an incomplete story.
