Monkey bones (medium ninja)

Monkey bones are a form of bones that can be obtained by killing Padulah, Duke, Oudai, Uodai or Ouhai. They are almost identical to normal bones, but give 18 Prayer experience per bone when buried instead of the usual 4.5. Monkey bones are also used in the Monkey Madness and Recipe for Disaster quests to make Monkey Greegrees.

The small or medium monkey bones dropped by monkeys on Ape Atoll are completely different from normal monkey bones and are not tradeable on the Grand Exchange.
