you cant(n)
beat bowser castle after the ship
I'm starting to get tired of people asking this question.
beat the last boss in the last castle in world 2 as mini Mario
you beat the world 5 castle being tiny.
on world 5 you have to beat the boss in the last castle as mini mario.when your supersmall.
You have to buy it with your star coins in the first castle on world one
super Mario bros 3 is ten times better than super Mario bros
Run then at the last second JUMP. You will go right over it.
You have to complete a Castle or buy something with your Starcoins to save. i no its pretty rubbish x ;)
I have no idea how but how do you turn small after you have defeated the big thing on the world 2 big castle?!
You need to have defeated the castle course bosses in worlds 2 and 5 respectively with MINI MARIO (this is important).
