You have to throw bombs at his head.
You beat the game when you are in Bowser's Castle in World 8 and beat Giant Bowser and Bowser Jr. Then you save Princess Peach.
Deafeat bowser 2 times and have princess peach on your team. (to get peach beat bowser jr in peach ice garden and you will get her)
Look it up at www.mariowiki.com they have her personality, but just be yourself.
I think he did, once. Ever played Super Princess Peach? Mario was CAPTURED by Bowser, along with several Toads, and Luigi. Peach became the heroine of the game, defeating Bowser single-handedly (if you don't count the umbrella, Perry).
I heard that you throw the bombs at the giant bowser face and he'll burn up.Have NT tried it yet.
You have to go right up to bowser and give him a kick in the ass. then he'll fly away. Repeat it several times until he says" I GIVE UP! I GIVE UP!'
are you talkin' 'bout Mario
you have to beat all of the levels and defeat bowser and bowser jr and save peach i recommend a giant
you have to beat world 8 FINAL BOSS. thereare two, but when you beat the second one, princess peach comes down and kisses Mario.
i have to beat bowser a lot of times then i unlock baby peach .........
It depends on what game you're referring to. If it's Super Mario 64, the roof is unrelated to Peach, but you need 120 stars. You need 70 to challenge Bowser to save Peach. If it's a Mario vs. Donkey Kong game, just beat all the levels, though it's Pauline, not Peach.
Here's a basic answer: You have to get to the Comet Observatory, get sixty stars, and go to Rosalina to fight Bowser. When you beat him, you'll save Peach. Then get sixty more stars and go to Rosalina again and beat Bowser, and then you have officially beat the game with Mario. Then, do it all over again with Luigi.
