An alien is on the loose at the Colossal Toy Factory, and he is trying to steal the blueprints of the top selling Commander Cool toys. Will Commander Cool (Shaggy) and Mellow Mutt (Scooby) be able to stop him before its too late, or will the competing Stu Pendous Toys become number one again?
Shaggy: (narration) Like, it was a spooky and scary night outside the gates of the Colossal Toys building, but inside, kids from all over were checking out Colossal's life-size Coolcave, along with a pup named Scooby-Doo.
Shaggy: Y'know, being a superhero is a breeze. As long as you have a little help from a pup named... Scooby: ...Scooby-Dooby-Doo!
