Some of Pixar's notorious Easter eggs are references to Pixar films that were still in production at the time of release, making them references to upcoming Pixar films. Although it hasn't been as consistent as some of their other Easter eggs, in recent years it has become a tradition for Pixar to put in each of their films a cameo of or an allusion to a character from their following film.
- A Bug's Life - Woody makes a cameo in one of the alternate outtakes during the end credits, an allusion to Toy Story 2.
- Toy Story 2 - Geri the repairman has a drawer of loose eyeballs, a reference to monster Ted Pauley in Monsters, Inc. when Ted grabs a handful of loose eyeballs and attaches them to his face.
- Monsters, Inc. - Clownfish, the main characters of Finding Nemo, are depicted three times:
- Finding Nemo has allusions to the two films that followed it:
- The Incredibles - A non-anthropomorphic version of Doc Hudson from Cars is parked in a street of Metroville during the final battle.
- Your Friend the Rat - WALL•E from the film of the same name is the driver of the vehicle on Mars. This reference is unique as this was in a short, not a movie.
- WALL•E - Carl Fredricksen's walking stick from Up can be seen upside down (with the tennis balls attached to the feet) on two occasions. Firstly, when WALL•E is about to pull across the magnifying screen the walker is sitting behind the iPod. Secondly, when WALL•E falls down from the ceiling of his truck (after being knocked there by EVE), he collides with the walker.
- Up - Lots-o'-Huggin' Bear from Toy Story 3 is placed next to the bed of a little girl.
- Toy Story 3:
- Cars 2 - A car-ified version of the DunBroch family tapestry from Brave appears in the Ye Left Turn Inn in London.
- Brave - A wood engraving of Sulley appears in the witch's hut. Although Sulley is an original character from Monsters, Inc., this cameo was advertised as an allusion to Monsters University.
- Monsters University - Toy versions of dinosaur characters from The Good Dinosaur appear in the Scare simulators used for the final event of the Scare Games.
- Toy Story of Terror! - The paintings hung in the motel room depict dinosaurs under a tree, another allusion to The Good Dinosaur.
- Toy Story That Time Forgot - According to director Steve Purcell, the three posters in Mason's gaming room were allusions to three of Pixar's then-upcoming films: Inside Out, Cars 3 and Coco.
- Inside Out - Giant statues of Forrest Woodbush and Arlo from The Good Dinosaur are seen in Riley's memories of the road trip to San Francisco.
- The Good Dinosaur - Hank from Finding Dory appears at the bottom of the water when Arlo learns to swim.
- Finding Dory - The driver of the truck heading for Cleveland at the end of the film has a Band-Aid with an image of Lightning McQueen on his right hand, in honor of Cars 3.
- Cars 3:
- Coco: As Miguel and Hector are on their way to the Land of the Dead talent show, an Incredibles poster is briefly seen, an allusion to Incredibles 2.
- Incredibles 2:
- Toy Story 4 - The pegasus on the side of Barley Lightfoot's van is seen on the bouncy castle at the carnival, an allusion to Onward.
- Onward - When Colt Bronco knocks over Barley Lightfoot's Dungeons and Dragons-inspired board game, in the left side on a bookshelf, you can see a music album of Dorothea Williams, a human jazz performer in the upcoming Pixar film, Soul.
