The funhouse mirror is an item from Freddi Fish 3: The Case of the Stolen Conch Shell.
The funhouse mirror is first shown on display as the official prize for Gill Barker's funhouse game. Once Freddi Fish and Luther play the game and win it with a high score, Gill gives them the funhouse mirror as a prize. They later use it to scare Claw out of his wits in order to get the flashlight. After that the mirror will be replaced with the flashlight.
