Go to the level with things on a conveyer belt that smash you. It is somewhere in the area that requires 15 DeeDees to get in. Get smashed until you die. Before the scene of Dexter with stars over his head, pause game play. This should be done when Dexter receives the last bit of damage to kill him. If done correctly, your health should be over 200. However, once you return to the game you will still lose a life.
