Plot: Mystery Inc. (Fred, Daphne, Velma, Shaggy and Scooby-Doo) are attending the grand opening of the Coolsonian Criminology Museum, the primere exhibit displaying the monster costumes of criminals they dealt with in past cases (Shaggy and Scooby look at the Pterodactyl ghost costume, which blinks at them, before running away). However, the opening is crashed when a reanimated Pterodactyl Ghost attacks. A masked figure (better known as the Evil Masked Figure) appears on the window pane, who promises to end Mystery Inc.'s career. He and the Pterodactyl escape with two stolen monster costumes, the Black Knight Ghost and the 10,000 Volt Ghost. Journalist Heather Jasper-Howe starts to slander the gang, insulting their poor performance, prompting Shaggy and Scooby to attempt to become better detectives. Velma finds a pterodactyl scale, noting its strange green tint.

The gang suspect one of their old enemies is responsible. After removing the deceased Pterodactyl Ghost's portrayer Jonathan Jacobo from the suspect list, they conclude Jeremiah Wickles, the Black Knight Ghost's portrayer and Jacobo's old cellmate is the prime suspect. Visiting his ancestral manor, they split in search of clues. Daphne, Velma and Fred go to a library in the mansion, while Shaggy and Scooby wander off further into the mansion. Meanwhile, Velma finds a book on how to make monster in Wickle's library, but they hear the cries of Shaggy and Scooby, who have run into a re-animated Black Knight Ghost. Daphne fights with the Black Knight Ghost, only to have him destroy her weapon. Velma defeats him by kicking him, before the group escapes back to their headquarters.
