this appears in baldis basics birthday bash
0th Prize starts out in his closet, which is near the cafeteria. After 2-3 minutes, he will leave his closet and begin sweeping the school, similar to gotta sweep. If you touch him while he's sweeping, he will sweep you to another place while making sounds. When he is done sweeping, he will return to his closet, and wait again until its time to sweep.
- 0th Prize originates from Baldi's Basics Birthday Bash, in which he was just an image on a wall in the ending
- Even though he was added in Dev. Demo 8, a poster in the detention room about 0th Prize was not added until Dev. Demo 10
- 0th Prize's voice was made using TTS
