Skeletal monkey bonemeal is an item that can be used to train Prayer at the Ectofuntus. It is created by taking Skeletal monkey bones to the top floor of the ectofuntus and using the bones on the grinder. Along with a bucket of slime, players may use a pot of bonemeal to make 5 ecto-tokens. The bones used in the bonemeal give 4 times the prayer experience when used to worship the Ectofuntus.
In order to bring the bones out of the dungeon to crush, a legendary pet must be used.
