|Species:||Stuffed Sock Bunny|
|Debut:||Grounded in Gloomsville (Opening Sketch)|
Mr. Buns is a stuffed rabbit that Ruby created from one of her leftover socks. The floppy, yet enigmatic Mr. Buns loves tea cozies and pretty much finds himself in the middle of almost all the action in the mansion. He also has a strange tendency to end up anywhere and everywhere. It is possible that Mr. Buns could be possessed.
