A young girl plays with her Scooby-Doo action figures. "Alright gang! We've got a mystery to solve." We go into the stop-motion animated world of her imagination where we see the classic Scooby-Doo adventure she creates with her action figures: spooky woods, lots of Scooby-Snacks, a mysterious monster, and a wacky chase! However real life intervenes when the family dog interrupts the girl's playtime in order to get at the dog treats she was using as Scooby-Snacks.
