When you go into the mansion where you 
get bow, there is a door on the side of
you. Go inside the door and there is a 
box and a vase. Jump into the box, then
the vase. When you jump out of the vase
you become classic Mario. If you leave 
the room the option will dissapear and 
you have to do the code again.

Note: 
You don't have to enter the mansion again.

If you run away from battle, you will 
lose coins. However, if you spin right 
after you run away, then jump, then spin
again you will lose only about one to 
three coins.
