One rainy night, Shaggy drives the Mystery Machine -- and wrecks it! He bumped the Mystery Machine at 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 ice cream, but these guys could ruin even his appetite!
