I'm not even sure what happened. I didn't think I was all that low on energy (maybe 80?), and I was only in there long enough to go to the vendor, and buy the snocones for the quest, maybe 20 seconds. After I bought the final, purple one, my rock popped up to tell me I won the quest. Before I could even click through it, I went straight to hell, all my snocones were gone, and now I have to wait 2 hours before I can play again.
If the place is that deadly, might be a nice idea to give just a weeeee bit more warning before sending people off on quests there. And even if you don't warn at the outset of the quest, maybe give a bit of one when you enter the area or something. (subtext, majorly P.O.'d here)
