Rarest pet = Pixie Queen (57 pedigree + fairy card). Drops from Smogger. Chance of getting it is like 0.1%. I believe what someone else said about only 3 people having frost hound. Let me know if someone else has it...
I actually got that my first time killing smogger and its not that rare
I dont know about THE rarest pet, but I know there is a silver colossus that drops in Grizzleheim from the Runed Devastator and I have only seen one person in the game with it.. I have farmed many, many times and not gotten it. So I would say this one is pretty rare. It looks like a really cool pet! Either it doesnt drop anymore or people just arent using it. either way its one of the ones i've seen the least of.
Seraph is not the rarest pet. I got 2 seraphs from the hydra pack. Ice bird is the rarest in my opinion (rare chance from fighting nightwing in ravenscar). I have been fighting nightwing for several hours without stopping, still no pet drop.
i'm not fully sure what the rarest pet is. but one of my friends told me it was the golden kraken or topaz kraken dont know which one it is called but you get it as a drop from the kraken at trition avenue VERY rare.
I got a life troll by a boss dropping it. I dont remember which boss, but I started to wonder if it was rare or not because I never see anyone with it. It's not a crown pet or at any pet shop I've seen in any world. So is it rare?
To give my imput in the whole thing with the Seraph pet being rare, I see tons of people with it so I don't think it is rare.
i have a life troll i think it is a boss drop in wizard city. not sure how rare it is, people probably just dont know about it.
I have changed my mind, rarest pet is Frost (not Ice) Hound. Or the KIfreegames pet, so rare no one knows what it is.
i got a summer dragon from kifreegames
I've been trying to get a Ice Hound the one header that gives ice-hound at epic i have hatched with and orthrus with my collossus about 12 times and have only gotten a collossus back but my friend has gotten 5 Frost hounds and i have not even gotten those so i am windering if Ice hound is even possible to get from a Orthrus Collossus Hybrid... Let me know.
