Disney-Pixar premiered the new Toy Story short, Partysaurus Rex, when they released Finding Nemo 3D last month.  The short features Rex (Wallace Shawn) getting a chance to cut loose and be a party hero to bath toys.  A couple nights ago, the short debuted on the Disney Channel, and now it has gone online.  I didn't get a chance to see the short in theaters, but after watching it online, I wish I had.  It's bright, loud, and colorful.  It's also pretty funny.

Hit the jump to check out Partysaurus Rex.
