Disney is famous for creating interrelated plot lines across its superhero blockbusters – from Iron Man to The Avengers to the television series, Agents of Shield. Now, the movie studio has confirmed a theory first suggested by a fan in 2013 — the animated movies made by its subsidiary, Pixar, also share a common universe.

In a video released by Pixar early last week, the filmmakers revealed many Easter eggs —a reference to visual clues hidden in the various movies that reward eager fans similar to a traditional egg hunt. These include the delivery truck from Toy Story’s Pizza Planet, which has made an appearance in every Pixar movie except The Incredibles. Some like Arlo, the protagonist, in The Good Dinosaur, had a cameo role in both Toy Story and Monsters University, long before the movie was made.

These, of course, are just a handful of the hundreds of fun Easter eggs waiting to be discovered. So the next time you are watching a Disney or Pixar movie, be sure to pay close attention for the subtle connections.
