That always happens, the hatch uncommonly gives a new hybrid. The animal will remain the same, of course! But you will receive different talents. The talents your new pet has, some are from the ninja pig and some are from your elephant. Not a glitch, very well supposed to happen.
how come when I hatched my storm elephant with my ninja pig why did it give me another storm elephant thanks, Nathan fire talon level 48
Some pets have an uncanny hold on graphic for some reason, Like the nutcracker and winter owl with these 2 it takes a while before you are able to change their graphic, Usually took me 4 hatches with their offspring to do it. Usually pet hatching is random but some pets seem to have a stronger hold on the graphic than others. Also if your hatching a school specific pet that graphic has a very strong hold on the turnout graphic also.
