The only documented Disney activity involving the Toy Story property is the creation of the Toy Story Midway Mania! attraction, an interactive 4‑D experience that opened at Disney’s Hollywood Studios, Disney California Adventure, and Tokyo DisneySea between 2008 and 2012. This attraction was designed by Walt Disney Imagineering and was explicitly inspired by the Pixar Toy Story franchise.
