Sonic: Night of the Werehog (Monster Transformation)

I get bothered when people call Sonic a "werehog". "Were" means "man"--a real werehog is a man who transforms into a hog. Sonic is already a hedgehog--all his transformation involves is growing claws and extra muscles and fur. Anyway, here's an animated short Sega put together to promote the new video game, called "Night of the Werehog." There's no time counter, but I can say that the TF is in the final third of the film. See it here.
