Loss of Lemmings: One
In quick succession, Jump one over the block, Jump again onto the steel, then Jump again out to the right, clicking the last one while over the left bolt of the steel. It should catch the left edge of the trampoline and drop. Jump to doge the tennis ball and get it to reflect and go left. Make it a Kayaker. Let it reflect to face right, and Balloon up to the top of the chamber, landing on the vaguely ``Q'' shaped island. Platform the gap from the tail of the Q to the steel - let this Lemming walk off and die. Jump another over the block, give it Magno Boots, and Laser Blast under the right hand end of the horde.
