Aside from the most evil & hard to catch of all wild pets (The Unborn "thing" which should never be named, the other which rhymes with schimphernawl, and Emerald Whelpling) my list is a bit longer.
Since no one in this game plays or groups up for anything anymore pet hunting & leveling is all that is left.Molten Hatchlings
laughed at me...& refused to show themselves other than gray or white....had to stone it to get it rare.
Not to mention the Wild Jade, Crimson, & Golden Hatchlings
who also mocked me.
Then there was the ever lovely yet irritating Baby Giraffe
down on the plains.... I still want to cry when I think of these so called babies. They are non-spawns of Hades!!
You think Silithid Hatchlings are difficult? Try those damn Sand Kittens
!! You can always find a sandstorm or two but not a damn rare Sand Kitten!!
Oh and don't even get me started on the truly maddening Baby Ape
! It rains more in California than it ever will on Jaguero Isle!!
This is my short list. Don't want to discourage anyone from the joys of battle pet collection & hunting.....
