Step one: Go to Party mode, make it 10 turns, a team game, put your partner as a hard charater then handicap your stars to make yours at 9. Also, make the area that Snowflake lake thingy.Step two: After deciding who goes after who, pause, and go to controllers. Make yourself into a hard COM charater.Final: You should be able to get alot of stars, as at the ice place you use Chain-Chomps to steal stars AND each player gets 5 stars, making 10 more stars for your team. Just let them do the work while you do something for a while.
