Beat the game.
After acomplishing all the areas and and levels. Beat all the boss' until you get to the last relam. After that one of the last areas is that you have to battle all the boss' again. After that you battle king dee dee dee. Now he takes about (i had 100 lives or was it 99) alot of lives so collect before entering the fountain area. Afte rking de de de then you will eventualy kill him. Hopefully. But it doesnt end there. The big nightmare appears after you dance with the king. And he takes one hell of a long time. Evetually you will finish.
