6. Pizza Planet Truck (Of Course)
Now this is the big one. Every Pixar fan worth their salt knows the Pizza Planet truck, seen most prominently in the Toy Story series (well, 1 and 2 -
3 felt that wasnt worth bringing forward either), is featured in every Pixar movie, aside from The Incredibles (director Brad Bird wasn't au fait with all the in-jokes at that time). A constant reminder of where the studio came from, theres been some really adventurous hidings in the past, most notably in Brave, where a carving of the truck was seen in the witchs workshop. As you can see in the picture above, the truck appears in Monsters University just outside outside the JOX house when Mikes riding Archie across campus (its to the left, hidden in the shadows). Here its definitely a case of being hidden in plain sight. Seeing the image out of context its easy to spot, but in the film, moving so fast with so many monsters about, it wouldnt be surprising if you missed it.
