WoW Petopia Community

I'm in game and I see a hunter, that's level 60, with the Ghostcrawler pet (also 60). I'm not aware of any other ghostly crabs, so how does he have it? Or did he log out a long time ago with the pet out and it stayed out?

My guess is that he had it before they raised the lvl cap or he is doing the "scale down and lvl with your friend " thing
