Snailfeet's bone

Snailfeet's bone is recieved by killing Snailfeet without any weapons or armour during the Goblin High Priest Miniquest. Once you recieve them you have to bury them anywhere in Yu'biusk. This grants th user 1750 Prayer xp. If you try to bury it anywhere except for Yu'biusk, you get the message "You should go to Yu'biusk before you bury this bone"
