I have two pets, a ladybug and a lizard. I want to hatch the two since the one has great healing spells while the other has healing current, which I want to add to my healing spell pet. The only problem is I'm looking to get the ladybug back and despite having hatched five times I keep getting the lizard. Is it possible to have a set of pets where it is just impossible to get the one parent? Or am I just having some bad luck? I just don't want to keep wasting money if the first is the case.
