Disney/Pixar announced a new Toy Story short film along with a new image. The new 30-minute short titled Toy Story of Horror will air this October on ABC. It takes place during a road trip where Bonnie's car happens to break down and she and the toys stay in a spooky motel. One of the toys goes missing and the rest have to unravel a mystery before it's too late.
Executive producer Galyn Susman mentioned that the short will focus more on Jesse (Joan Cusack) but will feature other favorites including Mr. Pricklepants and Trixie from Toy Story 3. It also will show the relationship Bonnie has developed with her new toys (aka, Andy's toys).
One thought going around people's minds, including my own, is if this new television short will be a lead into a potential Toy Story 4 or character spin-off film. I think it's more plausible to continue Toy Story this way with various short films, but they surprised us with a third full-length movie. There is nothing stopping them from making a fourth.
