Now we all know that the Pizza Planet Truck appears in almost every Pixar movie. But why? Is it really Pixar doing this? (This is just a fantasy, not something that could happen in real life.) Could it be- a spy? Sneaking it's way into Pixar movies so they can collect information and make good movies(or at least try to.) Could it be from Dreamworks? Was the driver of the truck the kid who sits on the moon and fishes all day?
