The animators at Pixar place “Easter eggs” in their films, or references to other Pixar movies. Here are some you probably missed…and boy are they twisted.

In the 2001 Pixar film Monsters, Inc., the monster Randall Boggs (Steve Buscemi) tells monster Sully (John Goodman) that “humans skin monsters and make toilet covers out of their fur.” In the 2012 Pixar short film “Partysaurus Rex,” a little girl is shown taking a bath. In the bathroom is a toilet dressed in a fuzzy, purple-and-turquoise toilet seat cover—the same texture and colors as Sully.

In the 2015 Pixar film Inside Out, Joy (Amy Poehler) and Sadness (Phyllis Smith) visit the place in Riley’s brain where dreams are made. One of them is a nightmare about dead rats. That rat looks a lot like Remy, the main character in Ratatouille.

In the 2004 Pixar film The Incredibles, a French supervillain named Bomb Voyage robs a bank, leads a crusade against the titular superheroes, and escapes unharmed and unpunished. His whereabouts are unknown…until the 2007 Pixar movie Ratatouille. In a scene in Paris, the evil Bomb Voyage can be seen working as a street mime.

In the 2008 Pixar film Wall-E, Earth is left in ruins, with the environment destroyed and most humans living on a luxurious cruise liner in space. Amidst all the piles of junk and rubble on Earth: the Pizza Planet truck from Toy Story, the Hammy piggy bank from Toy Story, a race car from Cars, and a Mike doll from Monsters, Inc.
