One rainy night Freddy lets Shaggy drive his precious Mystery Machine- and Shaggy wrecks it! Luckily 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!
