Music
Electronic artist BT composed the music for the short. He said in an interview: "I’m in the middle of scoring a film for Pixar right now. It’s a short for Toy Story, and I’m not allowed to say the whole story, but quite literally, it’s like a Toy Story rave, and I’m actually not kidding either. Like, the toys get into all these shenanigans and it’s like pounding club music, this thing. So it’s really not very Pixar, but in like a really hysterical way, everyone laughs so hard when they see it. It’s really exciting to work with those guys."
