Beating the World 2 Boss
If you are playing against the World 2 Boss and keep on being killed on this level, try this trick. Now walk next to the magic lamp. It will start steaming. The Boss will show up. Hit him as many times as possible before he either starts firing cannon balls or runs to the side. When he is firing cannon balls, run around him in circles. He will not hit you. If you are playing with two players, have one person run around him while the other one fires at him, jumping the cannon balls if any are fired at the person who is shooting.
