Pixar were heavily involved in the creation of the Toy Box and Monstropolis worlds based on their properties. They collaborated with with Square Enix on the story, character design, and look of the worlds among other things and helped to design the Infinity Badge Keyblade. They even negotiated to have the story of Toy Box be set between Toy Story 2 & Toy Story 3. This went so far as to have Pixar suggest Andy's Room have the Starfield wallpaper instead of the iconic Cloud wallpaper, so the area can be chronologically accurate to the film series.
