Title says it all. In 1.8 add rabbits/bunnies as a pet, and as a side pet (like wither skeleton for skeleton, as an example of a side pet) add The Killer Rabbit of Caerbannog. Probably would have happened anyways, I suppose this is just a reminder for this pet being added.
+1 The plugin creator would have to add the pets and Andrew would have to add them into the configuration first.
I feel as though this will be added. No need to bump/+1, as almost all mobs in the game are pets. I believe this will be added whether Administration sees this or not.
