Mega Dangerous Bomb:
Kick a Rubber Bomb into a Dangerous Bomb.
Equip the Invincibility power-up or a Fire Suit, as well as some Speed, Bomb, and Flame-Ups if you can. Plant a bomb and right when it is going to blow,
place another one next to it so that in turn blows up. Continue to do so until the whole screen is filled and there is nowhere for your enemy to run.
