Inside Out: 22 Easter Eggs, In-Jokes And References You Need To See

17. A Sticker Of The Luxo Ball Is On Riley's Bag

One of the most common Pixar Easter eggs is the Luxo ball. The small ball the titular baby lamp in Luxo Jr. became obsessed with (or at the very least its star design) has popped up in many of the following shorts and feature films. How obvious those Easter eggs are has varied from the obvious (it's used by Buzz in Toy Story to fly/fall with style) to the obscure (it's only in the background of one shot in Up). The Inside Out appearance sits somewhat in the middle - it's seen in a flashback to a young Riley playing with Bing Bong. Note: The article originally stated the Luxo Ball appeared as a sticker on Riley's bag as the family moves house. This is only half correct - it's only the central star.
