It's more fun to find the eggs yourself. This way, when you finish you'll feel a bigger sense of achievement. If you've completed every island, this hunt should not be very hard for you. All you have to do is think about the item's surroundings, then think about what islands are set in that kind of environment.
Otherwise, if you are really stuck on the hunt, here are the cheats to help you save your time.
