Toy Story 3 Easter Egg - Syndrome the Townsperson

Go into Toy Box Mode and earn enough coins to purchase and build a tailor's shop or barber shop. Grab a townsperson and throw them in. Scroll down to the clothing option, and scroll to the near end of the list. There you will find the outfit of Sydrome, from The Incredibles. Pixar created both the Toy Story franchise and The Incredibles.
