Disney has just surprised everyone by releasing a video that connects all 17 Pixar movies, and it actually makes sense.

Pixar has built a massive world of beloved storylines and characters since the release of Toy Story in 1995, and devoted fans have spent years connecting the dots between them. No, they didn’t discover a hidden doomsday prophecy, but they did reveal what could possibly be one of the most intricate and long-running tales ever put to screenplay. Disney themselves have now confirmed at least some of those theories, such as characters recurring mysteriously in multiple movies.

Blogger Jon Negroni cracked open Pandora’s box in 2013 when he wrote an epic essay on the film saga, proposing a timeline from Brave to Finding Dory involving witchcraft, artificial intelligence, and post-apocalyptic survival. You can read the full story here, but be prepared for an intensive brain workout.

The best part about all of this? It’s a great excuse to have a fresh Pixar movie marathon.
