Loss of Lemmings: Zero
Make the first Lemming Platform the tiny gap between bucket and spade at the last second, so that none escapes. Jump one of the emerging Lemmings off the spade handle, and let it drop to the level below the beach huts. Make it a Runner and a Swimmer. Bash the palm tree, and Jump from the bucket handle. Let it reflect off the steel, then Jump again. Jump over the clam. Mine the beach huts, convreting to a Basher on reaching ground level. Platform the gap and Bash the bucket. Bash the beercan on the way back.
