you have to complete bowser castle aka mibus castle right now in the game then you have to be Mario and lugi go to toad town and open the gateway to princes peach castle.
you do some stuff at Bowsers castle to go to peach castle
Princess Peach lives in her castle but is with Bowser most of the time
you do some stuff at Bowsers castle to go to peach castle
you go to peach's castle, beat blizzard midbus, go through airway, beat dark star 1, go out the front of peach's castle, defeat peach's castle, go to the place where you first fought bowser in the beginning, and there he is, dark fawful.
in a castle with peach
I'd say a lot of hard enemies are in Peach's Courtyard and inside Peach's Castle. The ones in Peach's Castle are harder though. The hardest enemy would be Dark Mechawful. (He's a blue robot looking guy and he's in Peach's Castle) Hope I helped!
That question doesn't make sense please retype that question they probably mean where is the switch in peach's castle and in Mario 64
Peach is with Bowser locked away in her own castle and Mario must save her with his friends.
When Mario repairs the castle with the star that bowser gave him peach comes. she says "Mario! the power of the stars has repaired to the castle. And it's all thanks to you. thankyou Mario." then peach kisses Mario and bakes him a cake like she promised. and when you get 120 stars go ontop of the castle, talk to Yoshi and he gives you 100 lives.
in the Mushroom Kingdom near Peach's castle!
Beat Bowser the 3rd time on the top floor of Peach's Castle. It takes 3 bombs to defeat him.
keep trying!!
