List of Pixar film references
Beginning with "Red's Dream" and its references to previous Pixar short films, Pixar has included references in its films to other works produced by the studio. These have included cameo appearances, references to characters, objects, and titles of works. Additionally, such easter eggs or in-jokes can refer to Pixar staff, associates, or places or events from the company's past. Lastly, some things, such as A113, Pizza Planet, or actor John Ratzenberger have appeared in the majority of Pixar films, establishing a set of traditions that subsequent Pixar films try to include. The  following is a list of all documented self-referential nods contained within Pixar films and shorts that the various filmmakers have incorporated into their movies. Traditions. A113. A113 is an Easter egg that has been inserted into several animated television shows and feature films as a homage to a classroom at CalArts, the alma mater of Pixar/Disney executive John Lasseter and director Brad Bird, among others. Bird was the first to use the A113 Easter egg, on a car license plate in an animated segment entitled "Family Dog" in a 1987 episode of the television series "Amazing Stories". John  Ratzenberger. Described as "Pixar's good luck charm" by John Lasseter, actor John Ratzenberger has played a role in every Pixar feature from "Toy Story" to "Onward", including a few not produced by Pixar. "Soul" is the first film where John Ratzenberger uses his likeness instead of a voice role, while he is not present at all in "Luca" or "Turning Red". Luxo Ball. A yellow ball with a blue stripe and a red star, which was first shown in the short "Luxo, Jr.", has been shown in the Pixar logo sequence and several Pixar feature films and shorts, most  prominently in the "Toy Story" franchise. Pizza Planet. Pizza Planet is a fictional pizza restaurant that appears in "Toy Story". In the film, it is a large, sci-fi-themed restaurant with arcade games including robot guards at the entrance. The company runs a fleet of derelict Toyota Hilux pickup trucks (as evidenced by the inscription on the tailgate; it is a Toyota inscription with the first and last two letters, "TO" and "TA", worn off so it simply appears as "YO") with a rocket on the roof featuring the restaurant's logo, as seen in "Toy Story", "Toy Story  2" and "Toy Story 3" (though in "Toy Story 2", the truck model is called a "Gyoza" as seen on the owner's manual). There is a Pizza Planet reference in every Pixar feature film to date except for the film "The Incredibles". Lee Unkrich has said that there is no Pizza Planet truck anywhere in "The Incredibles". Companies. To avoid overt product placement in Pixar films, a series of fictional companies are used as placeholders. Some appear only in one franchise (such as fictional NASCAR sponsors in "Cars") but others serve as recurring themes. Buy-n-Large (BnL). Buy -n-Large is a fictional mega-corporation that first appeared in "WALL-E" as the entity which controlled all economic and government services on the future Earth. Dinoco. Dinoco is a fictional oil company that first appeared in "Toy Story" as a small gas station. It plays a central role as a key race car sponsor in "Cars", and made a small cameo in "WALL-E". The company's logo is a dinosaur, but with a "Brontosaurus" in "Toy Story" and a "Tyrannosaurus" in "Cars" (a reference to Sinclair Oil, which uses a similar dinosaur logo. The name, however, is  similar to Sunoco, the current oil and gasoline sponsor of NASCAR). Eggman Movers. Eggman Movers is a fictional moving company that has an anthropomorphic egg with a hat as a mascot and appears mostly throughout the "Toy Story" franchise. The company's name is a reference to Pixar production designer Ralph Eggleston. Poultry Palace. Poultry Palace is a fictional chicken-based fast-food chain that first appears in the Toy Story short "Small Fry". Movies. Section::::"Toy Story" franchise.
