The Zuu is a flying enemy from Final Fantasy IX. The party can find the Zuu in the tree on the way to Cleyra, and it only appears alone. Its Aera attack is fairly strong, doing around 200 damage, and its Swallow removes a character from battle.
There is no way to retrieve the swallowed member for the duration of the battle, and that character will not gain EXP or AP upon the Zuu's defeat. Eating it gives the Blue Magic spell White Wind, which can be useful at that time in the game considering Dagger, the party's main healer, is not usable.
Anzû, before misread as Zû, is a lesser divinity or monster in several Mesopotamian religions. He was conceived by the pure waters of the Apsu and the wide Earth, or as son of Siris. Anzû was seen as a massive bird who can breathe fire and water, although Anzû is alternately seen as a lion-headed eagle (like a reverse griffin).Zu means "fire" in the Sumerian language.
