Trivia: The Crypt Keeper's eyes are actually taken from another famous animatronic monster... Chucky the killer doll! The Crypt Keeper was made by the same special effects wizards that created Chucky, and they decided to reuse some of the eyes they made for Chucky when they created the Crypt Keeper puppets, since they fit the design. (Albeit they were ever-so-slightly repainted to look a bit more "rotted").
