This is your heads up that the quest, Green Dream Team, is currently still bugged!
Here’s the link to Lazey’s comment on how to avoid waiting for a hotfix so you can get this pet when you unlock this quest: https://www.wowhead.com/ptr-2/item=210785/snorr#comments:id=5708578
I got the pet and completed the quest, then it gave me the quest again and the pet I need is no longer even listed in the vendor.
same , can not purchase snoor not in shop to buy 2nd and only quest from npc
Guess I was lucky, hadn’t seen Amayita’s link to a workaround but still had no problems getting Snorr.
I saw your post about the workaround but forgot about it, though. I was able to get Snorr anyway.
This morning I saw the same quest pop up again. I can see & re-purchase Snorr. My problem is I don’t want to learn it again to get credit for the quest. I don’t like multiple pets I can’t cage.
And it still seems to be bugged. I can’t complete this with the steps provided in the game.
You all make a fantastic game! Please make this part of it consistent with the rest.
Thank you! 
The only new pet content in the game and it’s busted. Par for the course.
