In World 5-3, go up the ladder. Pick up the turtle shell and toss it. Wait for Bob-ombs to appear get points in this order: 200, 400, 800, 1000, 2000, 4000, 8000, 1-up. Let the turtle shell roll more and get more Albatoss to drop more Bob-ombs to get to as many lives as needed. The maximum number of lives that can be collected is 99.

Go the through the first level as fast as you want. When you get to a log that leads over a ledge, go into the door to the right of it. You will see a vine that leads up to a higher point. Go up that vine. You will see three bushes and five enemies standing to the right. Pull the third one closest to the enemies and you will get a huge turnip. Throw the turnip at the enemies when the first enemy is on the ground. The turnip will bounce until it hits the next one and so on. If done correctly, you will get an extra life. Keep doing this to get as many lives as needed.

When you pick up a turtle shell and launch it, any enemy on the ground it hits will give you a heart. Hit multiple enemies for points.
