Ouhai will appear if players talk to a monkey on Ape Atoll while in human form. He may appear along with one or two Monkey Guards. He is similar to Padulah except that he cannot be killed normally. If he hits the player, the player will appear in the Ape Atoll prison. Other guards such as Oipuis and Duke can appear in the same way. Monster Examine states that his max hit is 216, however, he does not do any damage when he knocks the player unconscious.
