Some people say it's the punch line to an old joke, but in this case it's serious! Why else would Russell the Hedgehog from Once Upon a Forest wear a belt?
This artwork was requested by "Fox-Pixar" of DeviantArt. Guess he thought Russell should wear a belt as well.
I admit I had to do an image search for the character, since I never saw the movie.
Character based on The Furlings by Rae Lambert
