"Race to the Finish"
"Haunted Castle" is the 8th episode of the first season of Inspector Gadget.
Gadget, Penny, and Brain are in Transylvania, searching for the crime fighters' convention. Arriving in a place where the convention is, Gadget gets an another assignment from Chief Quimby: Claw has set up a hideout in Count Dracula's castle and that he's planning to infiltrate the convention and Gadget has to stop him. Gadget takes Penny and Brain along to the castle. Claw sets spines to do the trio in, but fails. While exploring the castle, Brain is totally frightened because he's afraid of ghosts, but Gadget and Penny are not because they believe that there's no such thing as ghosts and that it's all a superstition. Claw decides to split the Gadget clan up by throwing a tennis ball so Gadget can take it right to a trap. Brain follows Gadget, while Penny goes to the basement. Penny discovers the secret passageway in the basement, but she gets captured.
Meanwhile, Brain rescues Gadget in the nick of time and they go to the basement to find Penny. They get thrown into a dungeon where they find Penny. Claw burns the dungeon into flames to finish the trio, with the help of a toy mouse, but they escape. Dr. Claw separates Gadget and Penny from Brain and he puts them in a pit, where the walls with spines begin to move.
Brain is now being chased by the M.A.D. agents disguised as a werewolf and Frankenstein. This attracts Chief Quimby and, feeling that Gadget may be in trouble, goes to the castle with the other policemen. The agents are arrested, Brain rescues Gadget and Penny, and Claw escapes.
- This is one of the few times where Gadget is useful and dependable.
