Looks like he snuck something inside the pumpkin to help you escape. Probably a bomb. You are going to have to remember to give him a promotion when you get out of here. Or at least reduce his daily newspaper floggings.

Too bad they confiscated your knives or you could slice the thing open neatly. Maybe even carve a funny face into it. Heh heh, you bet you're the first guy who ever thought of doing that.
