While playing, execute a fire punch or a dragonball, then quickly hold SQUARE and press R1, L1, CIRCLE. If you did it correctly, one worm from each team will be teleported to a boxing ring where all you can do is punches and dragonballs. When one of the worms dies you will teleport back to the original landform.

At the Weapon Options screen, press X + Square 10 times. This code also lets you swing 360 degrees with the ninja rope.

When you have a banana bomb, walk up to a wall with a worm near it.... make sure you are against the wall and that it rises above you at least half an inch...also make sure the worm you are trying to kill is also close...when nextto the wall, aim strait ahead and chargeup fully and the bomb will get stuck in the wall...when it goes off it will do max damage to any worm near it. easy kill... (note: you will lose your worm also...last resort only)

If you go to the weapons options screen and hit Down, Right, X, ?, ?, X, ?, ?, X, ?, ? you will recieve infinite banana bombs. NOTE: not for use with the upgraded weapons code (X+? 8 times)

Begin a match and press X as the gamebegins to generate a landscape.You can now change the code to anything you want by pressing the directional pad.
