Monkey corpses are what is left after killing a level 3 monkey. The player must have started Tai Bwo Wannai Trio in order for a monkey to leave its corpse behind when killed. Players who have yet to begin the quest will receive the monkey's bones instead.
During the quest, the monkeys will evade the player's melee attacks and therefore must be killed using range, magic, or a halberd. After the quest is complete, the player may once again kill monkeys using melee and will always receive a monkey corpse unless they are on a free-to-play server.
A monkey corpse may be used as an alternative to monkey bones when creating a Karamjan monkey greegree during and after Monkey Madness I.
If a player attempts to use a knife on it before starting the below quests, they will receive a message saying: "You don't know how to skin a monkey...yet." although the player will receive this message even after they have completed the quest, since the player does not end up skinning a monkey themselves.
The monkey corpse is skinned with an NPC's assistance during the Tai Bwo Wannai quest, which yields a monkey skin. The monkey skin can be combined with a raw seaweed to create the seaweed sandwich requested by Tinsay. Alternatively, using seaweed on a monkey corpse creates a useless stuffed monkey.
