Where is the baby turtle in golden sun the lost age?

There is an animal trading sequence on all of the small islands which basically only have one house or place each (no villages, inns etc like on the bigger islands)and are called things like SE Angara Islet etc. You get a pretty stone by helping two penguins, give it to a bird in a nest and get a fancy red kerchief, give it to a cow and get milk in return (you need the ability Sand for that). Give the milk to a thirsty little dog and you get the turtle. When you have an item you have to read the animal's mind to find out what they want, you will then give it to them automatically.
