I was fishing in Dalaran sewer.
All of sudden, I was sheeped, and then I started looking
around to search for the culprit, but without
any result unfortunately.
I brought the doubts with me and left Dalaran.
After a while, Minigob Manabonk sent me a mail
and admitted his acts, but he gave me The Mischief Maker
so that I could "manabonk" my friends on his behalf.
I think the best may be use it back on him when I
see him again.
