Bats are mounts in the Inside Out Play Set. They eat one of Riley's memories in the levels "Brainstorming Phase 2" and "Looking for Treble Phase 2" and turn into a ball allowing you to ride them. They are not unlockable in the toy box. They are mentioned by Sadness with her saying that she thinks they are funny.
- It is unknown why they are mounts in the game because they were enemies in the trailer.
