Please make sure you use the right DS. The type of DS this is on is the Nintendo DS Lite. Go to the bob-bomb battle field level/picture. Go to the cannon near the ? brick. Go in the cannon and blast your self at the sky under the grass slop. You will hit the force field and fall down. You will lose half aof you life. Do this once more and it will look like you died on the grass slop. Which makes no sense since gravity didn't pull you down.
