I've beaten Thetis, Queenbee, and the guy with a guitar.. Now I'm supposed to enter the Quarry. I don't know where it is or how to do it. A guide said use Thetis's charge to hit the Bubble at the left of hunter's camp where I had used Queenbee to lift up a blocker, but Thetis's charge is an ice dragon which can't hit it. I hope this isn't too confusing. So, how do I get into the Quarry?
