5 STARS ON YOUR SAVE DATA!!

Do you want to learn how to get those 5 stars on your save data ?

I'll tell you how:

1. You must clear the game (beat world 6)
2. You must gather all the star coins (from world 1 to world 6 including the mushroom and the flower world)
3. You must open all paths that cost 5 star coins and find all the secret ways
4. You must gather all the moon coins (from the star world)
5. The last thing you must do is to get 3 crowns (you get the first crown when you reach 1000 lives,the second when you reach 1100 lives and the third when you reach 1110 lives)

NOTE THAT :if you have used the white raccoon mario to get some of the star coins (and moon coins) or to win some levels you won't be able to get some of the stars .To get them you must collect these star(/moon) coins again or to win these levels without the white raccoon mario.

ONE OTHER THING IS THAT:

when you get the three crowns mario removes his hat and he puts it back if you lose a life
