Ancient gorilla greegree

The blue gorilla greegree is made from a monkey skull, which is currently unobtainable. When wearing this greegree on Ape Atoll or some places in the Ardougne Zoo, the player will turn into a gorilla with a blue face. This item has existed since Monkey Madness was released, but is currently obtainable.

The chathead of the blue gorilla is black much like an Elder Guard, rather than blue which is how it appears in-game.
