Iwazaru is one of the three wise monkeys who reside in the Temple of Marimbo. He interacts with the player as one entity with Mizaru and Kikazaru, and they help players during the Monkey Madness I quest and Freeing King Awowogei subquest of Recipe for Disaster.
Iwazaru is mute, but he overcomes his disabilities by co-operating with the other wise monkeys and communicating via sign language with them.
- Mizaru (見ざる), Kikazaru (聞かざる), Iwazaru (言わざる), can be translated from Japanese as "Don't see, Don't hear, Don't speak", where the word "-zaru" (猿) can also be translated to monkey (猿). The three can also be translated as "See no evil, Hear no evil, Speak no evil." The maxim, Three wise monkeys (san'en, 三猿), is Japanese in origin.
