We decide to double back and check secret passage we missed while me still big so it easier to get up. Nature boy shapeshift to try and scout ahead while we wait. Apparently, he not so stealthy as we hear sounds of battle. Eventually, we see ice-gargoyles come and attack us. We defeat them, and then able to scout out rest of area. It lead to hole facing outside, perhaps for defenders of place to be able to toss rocks to crush people at gate. We find secret room to take short rest.

We then go back to statue room, and go to explore mysterious room to side behind giant iron chain curtain style door. It seem like mess hall/throne room. Paladin guy walk ahead to check throne, when bunches of yeti show up and attack. Devil girl blasts them with big fireball, but then noise wake up giant polar worm which crawl out of pit in center of room. 

We carve through remaining yeti to try and flee, though it look like yeti not friends with polar worm either. Nature guy try to see if we escape to room Yeti came from, but he end up running from there, since yeti chief was there. While polar worm and yeti chief size each other up, we make tactical retreat in chaos, maybe hit them after they weaken each other.
