Trivia

 * The Mister Munchy character seen on various decoration items is the mascot of a popular snack brand. The character's design and use as a logo parodies the Pringles logo.
 * The monkey-crab cushion decoration items were at one point given out via a lottery to participants that collected the barcodes from "monkey-crab" branded cereal boxes.
