Loss of Lemmings: Zero
Make the first Lemming Stomp at the right hand side, and make the second an Attractor. Stomp again by the castle, allowing the Lemming to relfect twice first, and while going right. Give it a Balloon and use the Fan to guide it all the way up to the top. Let it reflect, and Platform the gap. Bomb x5 from the top of the slope, making each bomb 3/4 of the way to the left in the crater left by the previous one, so as to break through down and left. Use this Lemming to Platform the stomped hole, or if it stops and dances, use one of the dancers (but NOT the attractor!). Release the attractor by making it a Platformer.
