The skeleton is a costume that may be worn by a mouse.
It was added with the Halloween 2014 event. Once worn, it will turn the mouse into a skeleton for 20 minutes. It also spawns as an Enemy in the first two maps of the Halloween 2012 event.
- When the skills were introduced in play (V1.82), the players revived with the Ambulance skill had the appearance of a skeleton, but was later changed in an unknown update.
