150
it depends on what you wanna do. if you wanna beat the game, then you don't have to collect ALL of the stars. if you wanna use the cannon outside of the castle, then you require all 120 power stars. TIP: There is a little surprise for you on top of the castle :)!
It is impossible
you must stand in the middle of the sun in the castle (you must have 14 stars) than look above you in the sunschine then you will get in the extra level end in the u will find the switch
