Bring a Baby Crocolisk to Old Man Barlo. You can find him fishing northeast of Shattrath City by Silmyr Lake.
Hello lad. I'm glad you've stopped by to talk to this old man--there's trouble back home.
A traveling merchant recently sold a batch of baby crocolisks to some gullible children. Crocolisks are wild beasts, and many have escaped and now lurk in city waterways.
Grab your strongest fishing pole and drop a line in Stormwind or Orgrimmar and bring one of the little devils back to me. I'm anxious to see one.
