FFIX - Sidequests - Friendly Monsters
Sometimes, you will enter battles where the music is different from normal, and the enemies look slightly different. These are friendly creatures, and they will ask you to give them gemstones in exchange for AP and items. Each friendly creature can only be found in one area. They will not always show up first time, but if you don't help them the first time they appear, they will appear again. You do not have to help the friendly creatures in any particular order, but you can only help the Yan after you have helped all the others.
