The Grim Guzzler (Horde)

Alright this is oldskool for you youngins out there:

1. 
   
2. You'll see Ribbly right in front of you when you walk in... talk to him to pick a fight and kill him.
3. 
   
4. Summon Hurley by destroying the brew barrels in the room next door (same room as brewfest boss, or coming up from the entrance, the empty room to your left)... click on the three barrels to break them open and he'll come running in with his crew.
5. 
   
6. Plugger is on the level above walking on the bar table... next to are two tables with stuff you can pickup. Pickup the stuff and Pluggy wants to fight.
7. 
   

Oh, and after you kill Plugger the patrons of the bar have a nice surprise for you. You'll turn in the quest outside the bar if you keep turning left.

I recommend checking out [npc=9499]'s wares before you steal stuff off his tables and kill him. He sells Dark Iron Ale Mug which is needed for Spawn of Jubjub, and some other goodies as well. Rogues have a good chance of pickpocketing a key to the joint. Have fun... kill and swill.

In LFD, we had someone summon Hurley and pick a fight with Ribbly. Resulting in a party wipe. We couldn't re-summon Hurley. So careful when pulling these guys.
