Comma, the mascot headmaster (lead, unpaid, credit given)

Comma, the mascot and "Headmaster" (lead). A black-and-white plush creature with folded rabbit ears and a quill for a tail, who announces the rules of the killing game. It calls itself the narrator, the headmaster, and your best friend. It's cheerful, theatrical, and delighted by chaos, and it treats murder like a plot point.

Voice notes
Bright, bouncy, and playful, with a big storytelling energy. The unsettling part is that it isn't angry or cruel. It's having the time of its life. It can swing from sing-song to offended in half a line, and it should occasionally go unexpectedly soft and tender, which is worse. Please don't play it as a generic villain. It's a cheerful host who happens to be horrifying. An original take is welcome. I'm not looking for an impression of any existing mascot.
