Eggs

There are currently three Standard Eggs: Cracked, Pet, and Royal Eggs. There's also a Starter Egg, but that can only have one of three pets in it and you can only get one when you start out in the game. Some eggs you can no longer obtain, these are: Blue, Christmas, Farm, Jungle, Pink, and Safari Eggs. The Aussie Egg is the current egg you can find in the Gumball Machine!

You can only get Safari Pets from the Safari Eggs; also you can only get Jungle Eggs from Jungle Eggs. This pattern continues with other limited eggs such as the Christmas Egg, Farm Egg, and Aussie Egg.

However, there are some pets that cannot hatch from the eggs
