The New Scooby-Doo Movies - Season 1 - Eps 2: The Dynamic Scooby-Doo Affair
When The Mystery Machine breaks down (as is expected) the gang bump into smugglers (loading crates into an airplane), Batman and Robin, a little old lady, and a punching clown filled with counterfeit cash. A tip leads them to the carnival. . .where they find Joker and Penguin behind the kooky counterfeit caper. As is usually the case with these villainous villains, our heroes wind up in a funhouse hideout.

Synopsis
Aside from doubling the length of each episode, The New Scooby-Doo Movies differed from its predecessor in the addition of a rotating special guest star slot; each episode featured real-life celebrities or well known fictional characters joining the Mystery, Inc. gang in solving the mystery of the week. Some episodes, in particular the episodes guest-starring the characters from The Addams Family, Batman, and Jeannie, deviated from the established Scooby-Doo format of presenting criminals masquerading as supernatural beings by introducing real ghosts, witches, monsters, and other such characters into the plots.
