Scooby-Doo? In Where's My Mummy?
She encountered Mystery Inc. when she decided to go after the treasure of Cleopatra, hidden under the Sphinx. However, she and her crew ran right into Velma Dinkley's Ghost of Cleopatra plan to protect the treasure. After avoiding the "army of the undead" and watching her henchmen seemingly be turned to stone, she finally reached the crown. In grabbing it, however, she set off a trap, flooding the tunnels. Amelia made it out of the Sphinx only to be caught in a prearranged trap set up by Fred, and have the crown snatched by Triple A's hawk.
- Von Butch is one of the few examples of a Scooby-Doo foe who is openly a villain and is not involved in a monster/ghost hoax.
