For those of you out of the know, the old Shattrath fishing daily (from Old Man Barlow) cycled between 4 quests, one of which could drop Baby Crocolisk pets.
These are only only only available from the quest "Crocolisks in the City," where you go to Stormwind or Orgrimmar and fish until you get a baby crockolisk and go turn it in. The other 3 dailies will not drop pets.
Warcraftpets has notified us that the pet drop rate for these suckers has been upped to about 50%!! It used to be, like, .00005% or something (exaggerating? maybe). This is a great time to dig in your heels and finish off your fishing pet collection.
I've started a thread in my guild forums where we let each other know when the quest is up on our server and suggest you do the same if you have fellow pet collectors around. :)
