"This stone has been said to posses dark magic powers. According to Slytunkhamen, this stone houses the spirit of Anubis inside, and if it is ever released, chaos is sure to come. This can be seen by the radiant purple energy surrounding it. But if someone tries to release it, no one is dumb enough to do this. Right?"
The stone is located at the back of the Main Pyramid. Only Sly's Witch Doctor costume can reach it.
