Elsa Dress Moana Cosplay 4

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 items, 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.

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.
 * Toy Story trilogy – License plate number on Andy's mom's minivan, later replaced by a CUV in Toy Story 3.
 * A Bug's Life – Code on cereal box as Flik enters the bug city.
 * Toy Story 2 – Airport announcement for "LassetAir Flight A113" (also a reference to director John Lasseter).
 * Monsters, Inc. – One of the pillars inside the company reads "A13". The stars also make the marking A113 after Randall gets thrown in the door.
 * Finding Nemo – Model code on camera used by scuba diver.
 * The Incredibles – Room number in Syndrome's lair (not seen, only mentioned by Mirage). Also, the prison level where Mr. Incredible is held is "Level A1" in Cell #13: A1 & 13 and as, Elastigirl looks to the computer, in the "Level A1" diagram, the higher column is labeled "13".
 * Cars – The number of the freight train that almost crashes into Lightning McQueen while he is first on his way to Radiator Springs. It is also Mater's license plate in both the film and the related short film, Mater and the Ghost Light.
 * Ratatouille – Git, the lab rat, has a tag on his left ear that reads "A113". Also, when Linguini falls asleep to the old movie, A113 is seen on the screen.
 * WALL-E – A113 is the code for the directive given to the Axiom's autopilot to never return to Earth. This to date has been the largest involvement of the "A113" easter egg in the plot of a Pixar film.
 * Up – A113 is the number of the court room.
 * Cars 2 – A113 is the number on Siddeley's tail. It remains the number on Mater's license plate, and it is part of the image number on the spy photo of Miles Axelrod's engine.
 * Brave – A113 is written in Roman numerals (ACXIII) above the entrance to the witch's shack.
 * Monsters University – A113 is the classroom of Scare 101.
 * Inside Out – When Riley is walking up a street in San Francisco going towards the bus, she stops to see who is calling her. In the background, "A113" is written in graffiti on a building. When Riley Anderson heads to her new school in San Francisco, she is put in room A113.
 * The Good Dinosaur – A113 can be seen in a formation of sticks.
 * Finding Dory – The tags that are seen on Fluke and Rudder read "A1" and "13". The license plate on the truck then reads "CALA113", referencing to California Institute of Arts A113.

 * Coco – The office in the Bureau of Family Greivances is numbered A113.
 * Incredibles 2 – At the end of the film, the Parrs about to drop Violet and Tony off at a movie. On the marquee, the film is called Dementia 113, but one side makes it appear to read Dementi A113.

 * Monsters, Inc. and Monsters University – Abominable Snowman
 * Finding Nemo – School of fish
 * The Incredibles and Incredibles 2 – The Underminer
 * Cars, Cars 2, Cars 3 – Mack
 * At the end of Cars, there is a drive-in theater that shows John Ratzenberger as some of the parts of the movies, which are car-versions of Toy (Car) Story, A Bug's Life, and Monster (Trucks) Inc. Mack even notes that they keep using the same actor again.

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.

It acts as an obstacle in Babyface's minigame (where Babyface had to steer the toys down the stairs, trying not to step on any obstacles).
 * In Toy Story 2, one Luxo Ball appears in a TV commercial for Al's Toy Barn.

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.
 * In Toy Story, Woody sees the truck at the gas station and tells Buzz it is a spaceship with hyper-active hyperdrive which they head on it to the restaurant itself.

An actual Pizza Planet truck can be seen in a parking lot when Carl has a fantasy of leaving Russell. At the end, when Carl takes Russell and Dug for ice cream, the real Pizza Planet truck can be seen parked.
 * In Toy Story 3, the Pizza Planet truck is the vehicle that Lots-o-Huggin' Bear, Big Baby, and Chuckles rides on to get around Sunnyside Daycare. Pizza Planet is also seen as a calendar sponsor.
 * In Cars 2, Todd the Pizza Planet truck is attending to the Radiator Springs Grand Prix. He also appears in the background of a triptych poster of the movie, in front of Buckingham Palace.

Pizza Planet restaurants at Walt Disney World's Disney's Hollywood Studios and Disneyland Paris are named after the site in the film and are designed to resemble it. Disneyland features a similar restaurant "Redd Rockett's Pizza Port", which shares similar themes and designs.
