Bonemeal

Bonemeal is an  item that players need during and after the  Ghosts Ahoy   quest. It consists of a  pot  filled with  bones  (need not be normal bones) that have been crushed in the bone grinder at the  Ectofuntus .

Along with a bucket of ectoplasm, 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. They are sorted separately per type of bonemeal in the bank account but are all labelled Bonemeal. You can get the type via the Examine option of the pot. It shows: "A pot of crushed [type of bones]."
