Easter eggs are when people discover a hidden reference or familiar character from another source of entertainment, and these discoveries often fill them with excitement and joy. Many Easter eggs can be seen throughout Pixar's collection of feature films and animated shorts, and one of the most renowned is "A113," which is much more than just a random code.

A113 is the number of the classroom at the California Institue of the Arts where many professional animators, including Pixar staff, studied. What started out as an inside joke among graphic designers and character animation students became a homage to their school and a way for graduates to recognize each others' work. As a result, Pixar has referenced the institute's room number several times in their animations.
