The Scooby-Doo Show - Season 1 Episode 15 -

One rainy night Freddy lets Shaggy drive his precious Mystery Machine--and Shaggy wrecks it! Luckly for Shag, it wasn't his fault; he slid on a ton of popsicles laying in the street, right outside the Happy Humor Ice Cream factory. A trip inside to use the phone to get a tow truck turns into a mystery, complete with three Technicolor Phantoms--Chocolate, Strawberry and Vanilla! Scooby might love food, but these guys could ruin even his appetite!
