Fluffy was once a human being, but was pinned and attacked by a white latex cat. It injected a white latex substance into him, which was supposed to make him a white latex, but turned him red instead.
Fluffy stands around 5'3, has bright red fluffy fur, acts like a cat, has a big fluffy tail, two perky ears, white mask, and two red eyes. It can't speak, and only speaks in "meows" or "purrs" or for some reason when it's 'in heat' it goes "uwu" or "owo" when curious.
