I was playing today and my pet creeper was being annoying and getting in my way so I changed it into and enderman so it couldn't get in the 2 block high gap. I then discovered creeper pets can't be spawned in the game anymore... I would like them to do so and I have no idea why you took them out.
I am a 100 donor and have a creeper pet. I can't help on this one as I don't think that you can get one 50- donor.
