I have got 119 stars, then and went and defeated the last bowser wich should give me a 120 stars, but when I defeat bowser the princess says what she does then the credits come up and then a picture of a cake does. Then it stops at the cake. Is mine broken, or am I supposed to do something or what? I have waited up to 5 minutes but it just stays there and when I reset it, the game says that I haven't beat bowser. What am I supposed to do.
