Leave it to Pixar to take their films to the next level.
Earlier this month, Disney Pixar unveiled a short film on its Facebook page that connects many of its animated movies, fueling the super-fan theory that all of their releases are connected within the same universe, aka The Pixar Theory.
The video has garnered more than 11 million views so far, and in it we learn that Riley from "Inside Out" shows up at the aquarium in "Finding Dory." Not only that, but Arlo from "The Good Dinosaur" appears as a green dino toy in "Monsters Inc."
And it doesn't stop there.
