Luau Island is an island inhabited by Pigs and Idols. The main dilemma is that some of the pigs had gotten trapped by the Riptocs' security gate and are being kept to be the main course of the Riptocs' feast. Spyro then comes along to activate the gate switches and set them free. It has a lot of water and most of the gems can be found underwater. There is also a superflame portal where you have to flame three wooden tikis. Probably one of the easiest challenges.
