u know that you can ride the chicken things, and try to land on the blocks to win ruppes? well i just figured out today that when you fly out of the room imedeatly ride to the right. keep flying and you should land on a platform with 5 boxes.desroy them all. you will get 70 ruppes in total.
PS: do the spining attack to break the boxes. a regular attack will know the ruppes off the edge
