A year and a half after the events of Scooby-Doo 2: Monsters Unleashed, the gang returns to the Coolsville Criminology Museum for the Grand Re-Opening. When there, Scooby and Shaggy eat the whole buffet, Velma and Patrick will give a tour of the museum, and Daphne and Fred will answer some questions for the press. However, during this time there is a loud bongo drums and maracas, and then a wall bursts open, and an evil villain, who is dressed in all black, a Clone Trooper-like mask with spikes coming out the top and a cape with a huge E on it. He triumphently states:
|“Mystery Inc.! How nice to see you again, hows it going? It know how it's going for you: badly”|
and with that, he snaps his fingers and the Mamba Wamba costume starts moving, then the Mamba Zombie next to it, then the Lila statue next to it. The Mambas then throw smoke pellets everywhere, scattering everyone except Mystery Inc. and Patrick, who try and come up with a plan for this mess.
There are a total of 25 monsters Mystery Inc. encounters over the course of the movie. Monsters who's names are in green have a major role, while monsters who's names are in red have minor roles.
