Pixar movies are often connected! Hidden messages.

Pixar movies are often connected through hidden references and Easter eggs, as well as shared themes and characters. This has become known as the "Pixar Theory," which suggests that all Pixar movies take place in the same universe and are part of a larger, interconnected story.

One of the most well-known examples of this interconnectedness is the presence of the Pizza Planet truck in many of the movies, including "Toy Story," "Cars," and "Monsters, Inc." Another example is the appearance of the Luxo Jr. ball, which is seen in several movies, including "Toy Story," "Up," and "Monsters, Inc."

There are also more subtle connections, such as the presence of A113 in many of the movies. This is a reference to the classroom number at the California Institute of the Arts where many of the Pixar animators studied.

Overall, the interconnectedness of Pixar movies has become a fun and exciting aspect for fans to discover and explore.
