Over ten years ago, a fan named Jon Negroni developed a fascinating idea – the Pixar Theory. This theory suggests that all of Pixar’s movies are connected and take place in the same universe, with hidden clues and connections throughout – even in films like Cars and Brave. While the Pizza Planet truck is a well-known example, some of the connections are much more subtle. Now, Pixar’s newest film has added what many believe is the strongest evidence yet to support this popular fan theory in years.
The new movie Hoppers, a really good sci-fi film about the environment, includes several familiar nods to other Pixar films. You can spot the Pizza Planet truck when Mabel tries to rescue the animals from school – even a tortoise named Crush, a tribute to the character from Finding Nemo – and Dr. Sam’s lab is room A113. It’s a shame John Ratzenberger didn’t make a cameo this time around, but the movie is still full of Easter eggs. One reference, in particular, seems like strong evidence supporting the popular Pixar Theory. WARNING: Spoilers ahead for Hoppers.
How Hoppers Proves The Pixar Theory

So, at the end of Hoppers, they shut down the whole university program – and honestly, it makes sense, considering the potential danger to both people and animals. But it’s not all bad news! Dr. Sam, played by Kathy Najimy, gets to focus on her other experiments, which is awesome. She shows off a chalkboard covered in ideas, and I totally geeked out because three of them are clear references to classic Pixar films. It’s a fun little Easter egg for us movie buffs!
The sketches feature a “talking dog collar,” a robot cat buddy, and what looks like a cleaning robot—clearly Wall-E. The cat is a nod to Sox from Lightyear, and the dog collar references Up, specifically Dug and the other dogs Charles Muntz owned, all of whom wore collars that translated their barks into broken English. Earlier in the sketches, there’s also a Wilderness Explorer badge, referencing the troop Russell belonged to in Up. This all suggests Up might be set further in the future than previously thought, which is a bit tricky considering Carl Fredricksen was young in the 1930s. But ultimately, it’s an animated film, so focusing too much on timeline accuracy isn’t really necessary.
It’s a clever visual gag that really connects the Pixar worlds and supports the popular Pixar Theory from 2013. It’s just one of the many things that makes Hoppers a fantastic addition to all the Pixar films. Have you seen it? Share your thoughts in the comments and join the discussion on the ComicBook Forum!
