The Gang must help some familiar sounding actors.
Tropes:
- Actor Allusion: And how! Many of Frank's, Matt's, Grey's, and Kate's famous roles are referenced.
- Casting Gag: As mentioned above, Frank Welker, Matthew Lillard, Kate Miccuci, and Grey Griffin voice the gang and themselves.
- Mythology Gag: Several past villains from the franchise return, such as Redbeard's ghost, Captain Cuttler, The Creeper, and Charlie the haunted robot.
- Scooby-Dooby Doors: Played straight with several classic villains making cameos.
