Acquire Grunty Online
Grunty is no longer distributed by Blizzard, but some players sell the Heavy Murloc Egg through third-party websites or in-game via the Auction House.
Battle With Grunty
In pet battles, Grunty's Lock-On ability is a strong choice over Launch, as it has no long cooldown and deals higher damage output.
Avoid the Zergling
If a player summons a Zergling using the 
Zergling Leash nearby, Grunty will automatically engage it — and if the Zergling wins, Grunty is reduced to a steaming pile of mush.
