EAT MY SHRAPNEL !!
Number of lemmings that die: 1
Available time: 04:00
Turn the fourth lemming into an attractor and give the first lemming a balloon as late as possible. Immediately turn him into an exploder. Jump one lemming free and make him a climber. Jump onto the wall, when he's in the gap created by the exploder, give him a mortar. Make sure he falls back in the created gap. Now let him walk, when he returns to the left, platform over the water. Release the attractor.
