The Desert Boss

There should be a bigger more pyramid like pyramid when u go inside there is a coffin. The coffin will be a new item kinda like a bed. Inside the coffin will be chests and a skeleton. However if u take anything from the chest the skeleton awakes he grows bigger and grabs a giant sword he will try to kill anyone in his temple and if he kills u he takes his treasure back if u kill him he could drop a wearable crown and/or his sword. His sword will do good damage and long ranged. I also think u should add more animals
