It's actually too simple, cause every boss has an obvious weak point. Every time he swoops down, jump on his head. Make sure to Dodge his attack. Sometimes, I like to cheat. Go to any level, and wait at the finish until your time is exactly ?99 (?=any number) then go for it. You must finish with that time. A mushroom house will appear at the start. Go in and a mega mushroom will be put in your inventory after you hit the block. Go back to the boss, and make your way through the level. Once you make it to him, use the mega mushroom and stomp him a bunch of times. You should just have to touch him, but I'm not sure. his teqnique works for every boss. Besides the Giant goomba, which you still have to step on three times. This even works for the final boss. (FINAL final boss) all you have to do is ram the two over in mega mushroom form. That's how I did it because the level ws to easy to get by with that slot. I won it three ways, the cheat way, the normal way, and the mini way,(won with mini mushroom. I was curious to see what Peach did if she kissed mini mario. as it turns out, he just goes back to regular form). That's basically all you need to know.
Good luck.
