Easily Defeat Pilaf
A flaw in Pilaf's AI can make defeating him very easy if exploited. This only works the second time he is fought, just after the Red Ribbon Army level. Move so that Pilaf is just to your side. Jump into the air and hit him as many times as possible. Keep jumping and hitting Pilaf while remaining in the same spot. This will not completely stop Pilaf from being able to hit you. Just ignore any damage you take from Pilaf and keep jumping straight up in place while hitting him. He will not be able to do any significant damage to you by ignoring his attacks.
