A clip has gone online for the upcoming Toy Story short film, Partysaurus Rex.  In the short, Rex (Wallace Shawn) gets to shed his nerdy persona as he becomes a party star after saving bath time for some tub toys.  Like the other Toy Story shorts, this one looks cute, and it's nice seeing the beloved characters get to interact with toys you wouldn't think of, like in the previous short film where Buzz was in a support group with discarded Happy Meal toys.  Steve caught Partysaurus Rex said it was fun, and has a few Easter eggs in it.Hit the jump to check out the clip.  Partysaurus Rex will be attached to Finding Nemo 3D, which opens September 14th.[EMBED_YT]https://www.youtube.com/embed/9EuIo8VqHjs[/EMBED_YT]toy-story-partysaurus-rex-image
