The Pizza Planet Truck
The Pizza Planet Truck is a recurring easter egg found in most Pixar movies.
The Pizza Planet truck appears in almost every Pixar movie to date since Toy Story and is one of the most hunted Disney easter eggs aside from Mickey Mouse and the Luxo Ball, which both recur frequently in Disney-Pixar movies as well.
The truck first appears parked outside of a building near an intersection, and this is the clearest it can be seen in the whole movie.
The truck then makes a second appearance during Carl’s dream of hanging Russell out of the house by a rope of bed sheets. Below the truck can be seen stuck in a traffic jam and we see it backing out of a parking lot. The view is very faint, but can be clearly identified as a Pizza Planet truck once zoomed in.
The last time the truck can be seen is when Carl and Russell are sitting outside during the last scene of the movie pointing out red and blue cars. When the camera begins to zoom out you can faintly see the truck parked in the left parking lot. Again, a zoomed view may be necessary for verification.
