Luxo Jr Ball by Pixar

In every Pixar movie, Toy Story, Monsters Inc, Finding Nemo, etc. there is a small yellow ball, with a red star and a blue stripe. You have to look hard to find it, but it’s there. The ball was originally a central prop in the 1986 animated short Luxo Jr.

I want one of those balls – a real, small, inflatable one. Where can I buy a Luxo Jr. Ball? I’ve tried the Pixar website, no good. I’ve tried the Disney store, no good.

Someone out there must know this… anyone?
