You recover the piece of fur that Gurf had "lost" in his struggle with the murlocs. Return the fur to Gurf and let him know that the fearsome Murgurgula has been slain.
Is that what I think it is?
<Gurf spits on the clump of fur and tries to affix it to the hairless patch on his backside.>
This will have to do for now! Hopefully one of the <class> will be able to repair the damage.
