Pizza Planet Truck
The Pizza Planet Truck is a recurring easter egg found in most Pixar movies.
Around the 21 minute mark after EVE has landed on Earth and starts scanning everything, we see her enter sleep mode for the first time. After EVE wakes up she is treated to a present from WALL-E which is a junk statue of a robot which EVE eyes suspiciously before floating off.
Immediately after this EVE then proceeds to a nearby junk yard where she begins her search by scanning the engine of a broken down pickup truck. This truck is non other than the famous Pizza Planet Truck from Toy Story.
The Pizza Planet Truck is a famous recurring easter egg that began in Toy Story 1 and has since appeared in almost every Pixar film to date with the exclusion of The Incredibles.
