Skulk Rock Clean-up

We Wildhammers remember the past, more than our brothers in Ironforge. If you want to make friends here, then you get your hands dirty for us! The Horde abandoned their positions in the Hinterlands around Skulk Rock; it's now overrun with nasty sludges and oozes. We've got plans on that area, but first we need a clean-up crew to make a hole for us. That's where you come in, Sunshine! Head down there and take out ten green sludges and ten jade oozes, then report back to me here. Move out!
