I think you should be able to get every pet because, people travel so far for nothing. When they find out you cant get other pets from different worlds it stinks. I mean what is the point you do nothing but look at them wishing you can get it but never can. You can trade them too! Maybe you want a pet another person has but cant find it! All you have to do is trade!
I would make me so estacic to see something like a fire lion are ghostdog how cool would that be! How about you breed your pets and make different color pets like stripes with pink dots! I would love that!!!!!!
