The "Goat Monk" hybrid pet is the most rare pet in the game. It is hatched from a sheep and another random pet. The sheep is already almost impossible to get, as you have to be a staff member to get it; and another thing is that you will be lucky to hatch with the sheep from the few/many staff members.
The rarest pet is the death bat it is dropped by Kagemoosha Tree of Life Mooshu ( he is the first form of the death oni ) it takes 17 hours to hatch gives death bat card i currently just got it
With the Aquila expansion that was released a long time ago, I think the rarest pet is now the piranha hunter. It's only usable in pvp only, but has some Beast talents like may cast shatter
i disagree with this, they are a common item from many card packs, i have 6
I don't exactly have six, but yes, I was going to say, I got a seraph from a pack and it said "rare" not "ultra-rare" or anything like that (and I have discovered that the "rare" pets are actually more common than I myself would call "rare")
I was wondering if the yellow ghost is rare I got it from a boss I never see anyone with it :P
I'm not thinking its rare; I've gotten multiple yellow ghosts by doing a single pagoda; probably the reason no one uses it is because t doesn't give very good spells even when you fully train it.

I'm not cutting anyone down but I don't think there is a rarest pet, since all pets can be hatched, dropped or bought. Except the sheep. No one can get that pet because it's for members of KI and if they send you one.
