Nerf Arena Blast Cheats

Use one of the following values with the "open [level name]" code:

Go to the Ball Blast event and get all weapons and
ammo. Then, go to where you shoot the balls in (not by the water
fall). Use the jump thing to jump in front of the hole. Stand
there until you get all the balls. Shoot them in and keep doing
this until you get 100,000 or more points.
