There is no rarest pet, all are equally easy to get from hatching. The exceptions: Sheep pet: All hybrids result in a Goat Monk Pioneer Dragon: All hybrids result in a Frontier Dragon Stray Piggle: All players obtain one
I am not saying that all pets are equally rare. I am saying that there is no rarest, as it's very easy to get any of them and none are particularly rare.
I think that the rarest pet drop is the Life Troll from Krokopatra
I think that the rarest pet (in general) is the Sheep, limited only to the KingsIsle staff. You cannot hatch a Sheep, any hatch with a Sheep results in a Goat Monk. They did this so that there is no possible way to repreduce the Sheep, so it is REALLy only limited to staff.
I think that the rarest hybrid pet is the Pet Egg (hybrid). The Pet Egg (hybrid) is not the pet that you can purchase for 2,000 crowns in the Crown Shop. The Pet Egg (hybrid) is the result of Dragon + Colossus.
I hope you have found this post helpful :)
Um ... Not exactly you got the king isle stuff right but king isle staff only gave it to some people ( not kingisle staff) I have personally seen one
Lol The best pet i have on wizard101 is a sea dragon pet with health gift, spritely, one disarm card, and pain giver. I have a yuletide spirit that may cast unicorn. I also have a betta fish with may cast healing current and storm striker. My other good pet has may cast windstorm and some other good stuff i cant remember. I don't know what the rarest pet would be.
Noah DawnRider See you in the game I have a pagoda and like to share. Friend me
If you are thinking about commenting on some of the first responses, please read this! The individual who mentioned the Seraph pet had mentioned it before the Hoard of the Hydra Pack was released, which allowed everyone to easily receive it. This response was added when the only way of getting the pet was through drops by Stoker in Kensington Park. The other individual who mentioned the Stray Piggle, it was meant as a joke. Yes, everybody knows that everyone gets it at a low level. You will not be the first to solve the puzzle. Please read the dates of when some of these earlier comments were posted, so you do not sound ignorant when you respond. Thank you!
