if you get the stormzilla you can hatch it with a ather person

Well first you would need an adult wraith and an adult stormzilla. Once you hatch both of them together there is a 50/50 chance of you getting the pet that you already have or a hybrid pet called the grimzilla which is a combination of the wraith and stormzilla pet.
