Bonebeast

Bonebeasts are very very dangerous creatures. Their poison is enough to kill a relatively strong knight. Note that after you kill them, you can use their corpse as a xylophone. Due to them having no internal organs, they do not provide a very scrumptious meal, but they do make a very cheap musical instrument. They can be found deep inside the tombs of the undead mummies. Most bonebeasts do not bite, but some still manage to move their jaw muscles. It has been known that sometimes their jaw drops out in the middle of a feast.
