Just a quick PSA, I read a post on the US forum earlier about the new battle pet “Gurgl”. There is a shortish quest chain that starts at Breanni in Dalaran.
There is a walk-through on the front page of Xu-Fu.
One thing that was speculated about in the US forum thread was whether skeleton keys work on the quest where you have to open the cages and release the pets. I did it on a BS and can confirm that Laestrite Skeleton Key will open the cages. Though I didn’t use all 10 as you have to clear the mobs and they drop the keys (the normal way to do the quest). Whether scribes can unlock the cages I dont know.
