I couldn't find the post on us collating all our Spirit Beast info of I'd put it there. Ok, I hit 85 as fast as I could then passed out for a while, logged back in to the Abandoned Reef to camp the area when eventually at I think 6:12pm (Mannoroth server time) Ghostcrawler appeared at about the coordinates of 18.6, 66. Slightly North of the spot he was marked for on the map on someone's (very awesome and beautiful) spirit beast guide youtube video here, I forget her name, sorry!
He hit me a lot, frost trap didn't do anything to stop him. I have 92K HP and he brought me down to about 50-60K. He showed up as a Neutral Yellow spot on my minimap. He is VERY tiny physically, not like the other spirit beasts, so you really have to peer out to spot him.
I love him so much

Good way to hit 85 imo. Yay! (Sorry I'm on a Mac and have no idea how to take screenies but anyone on Manno is welcome to check him out when I'm in stormwind).
