Scotty is very, very well hidden on the island of Sra'vess, on the western edge of Townlong Steppes. If you've done any dailies for the Shado-Pan you've likely been sent to this location. In fact, you've likely been standing right by Scotty's house without even knowing it. This level 89 elite is camping out right under the mantid's nose at coordinates 21,47 on Sra'vess, but coordinates aren't going to get you very far, because Scotty's awfully clever.
His house is actually nestled in the roots underneath the tree in the middle of the island. In order to get to it, you need to sneak behind another house that is surrounded by mantid who aren't exactly happy to see you -- the same mantid you clear out for Shado-Pan dailies. If you head to the coordinates given, you'll see the mantid house, along with a bright purple bush to the left of the building -- I've taken a screenshot of the house and circled the bush for the purposes of illustration. Walk through the bush and behind the mantid house and you'll run face first into Scotty's abode. Don't expect Scotty to welcome you with open arms. He's kind of a jerk.
However, upon beating the snot out of Scotty, he'll drop Scotty's Lucky Coin. While it's not terribly lucky for Scotty, it's lucky for you that you happened up on it, because it will transform you into a pretty horrifying looking sprite for ten minutes. You cannot mount while wearing this disguise, and engaging in combat will cause the disguise to go away. In addition, the coin only has three charges -- but you can go back and visit Scotty again to grab another one if you like.
Scotty may be a level 89 elite, but he's not particularly hard to defeat. Interrupt his casts, and watch out for his 1001 Needles ability, because it's every bit as painful as it sounds. If Scotty doesn't happen to be there when you visit, worry not -- because he isn't a rare, his respawn time is relatively quick. As an added bonus, the sprites seem to have been given male goblin animations -- they laugh, they sit, they eat, they even dance. It may not be as random as Gok'lokk's Shell, but Scotty's Lucky Coin is just as useful for bizarre screenshot opportunities.
