Two giant monsters (named Humungonauts by Sheriff Stone) are attacking Crystal Cove. Suspiciously, each Humungonaut attacks properties owned by insurers Max and Jax Minner. Meanwhile, Scooby stumbles across Velma and Shaggy kissing, and discovers their relationship. Shaggy gets into a dilemma when Velma and Scooby fight over who he likes better, and he is forced to decide. Fred decides that the gang should have a name, “Mystery Incorporated”, in honor of those that came before them. Unfortunately he also decides that the gang should start wearing team uniforms. Once again Mr. E intervenes to help the gang solve the mystery.
