People who attended BlizzCon and received a card with a code on it could give their code to Tharl or his companion Zas'Tysh to receive the Baby Murloc. Zas'Tysh now stands without Tharl, who was strangely underwater in the nearby pond until it was fixed in patch 4.0.6.
Hail <class>. Didn't I see you recently at an exclusive gathering? You look familiar, but then again this city is a busy place.
If you attended that convention, then surely you were given a secret code. Tell me your code and I will give you a special prize in return.
