The Giant Ape only appears when a Pygmy is sacrificed. You can sacrifice a Pygmy on Ape Mountain by having a Possessed Pygmy winching it up on the sacrificial altar with the winch and having another Possessed Pygmy play the bongo drums. The Giant Ape will come and eat the Pygmy, and then wait for more food to be winched up. If a Pygmy is winched too hard, however, the islander will be torn apart and the Ape, in a rage, will crush the Pygmies at the winch and the bongo drums. The Giant Ape also dances to the bongo drum music.
Before the episode came out, it was expected that the Giant Ape would include a boss battle. It may have one in upcoming episodes, but as of now, this is just speculation.

- The term "ape" is a generic term used to describe chimpanzees, gorillas, and orangutans, but the Giant Ape bears the most similarity to a gorilla.
