So I just found Snowflaik and turned her in and was given Tortue, but I did not get the achievement for finding the turtle. Does it only count if you actually get him from the patch, and not from Jaxxon? I also have a bunch of Jaxxon's minions from prior years put away in my vault, and just noticed that I don't have any of the achievements for any of them, either. Can anyone shed some light on this please?

Yes, you have to find him directly from the patch. Same with the other minions, though I think some of them are retired? Since those only count for the year it was released.

edit: Just checked, and all the retired ones are Kawl, Oowel, Slivyne, and Eater.

glad I could help!

Thanks so much, that clears it up a lot.
