Ornament mice are found in the Festive Comet and are released around christmas time.
The disguise that this mouse gains from enclosing itself in a Christmas ball results in some interesting challenges when it comes time to grab the cheese. First, the mouse must roll the ornament carefully up over the trap. Then, it must thread its paw through the slots at the top in order to grab the cheese. Even if it escapes the trap in time, eating the cheese is a complicated ordeal. The life of an Ornament Mouse may be hard, but it still has a ball wherever it goes
