One strategy for Troll Marsh Level 23, Chicken Coop, is to swing the treasure chest to the right to drop it in the boat. For par, start at the top of the level. Drop the nest and troll simultaneously, followed by the egg and troll below. Release both remaining trolls to add enough bones to the lever to flip the Vikings into the boat.
