Shaggy & Scooby Doo Get a Clue (Werewolf Transformation)

The original Scooby Doo has to rank among the worst cartoons ever made, but the 2006-7 reboot Shaggy & Scooby Doo seems to cut from a different cloth, if the amusing clip below (taken from the episode "Super Scary Movie Night") is any evidence. And hey, it also features a dude turning into a werewolf! His name is Rusty, and in human form he's even kinda cute, in a very shaggy way (he looks a bit like Shaggy too) and wanders around rather endearingly on all fours. The transformation is quick but interestingly animated--if you pause to look at the individual frames, you'll see that the morphing is staggered, so that it waxes and wanes from frame to frame, giving the TF a shivery look.
