I don't know what it is, but as much as I enjoy these full feature "Toy Story" films, as little I think of the many animated short films they added to the franchise. Basically all of the supporting characters got their own big moment. This one here has Rex in its center and after being called a party pooper, he starts a huge party in the bathtub with a new bunch of friends. That's basically all there is to it. There is no heart in this short film, no real emotion and the fun basically all refers to the bathtub being turned into a gigantic discotheque. The new characters are okay to watch, but not too memorable. Also we don't really find out a lot about them. The writer and director is Mark A. Walsh and even if he worked on several other famous films again, this is his first job in both areas. Maybe a bit more experienced filmmaker would not have hurt. This short film is entertaining on just not enough occasions, so I cannot really recommend watching it. I really hope that "Toy Story 4" (guess it's coming at some point) will be as good as the feature films again and not as mediocre as the short movies.
