How to change the color of your bowling ball
After choosing your Mii for Bowling, hold one of the directions on the control pad on the Wii remote (left, right, up, or down). When the "Why not take a break?" screen, or whatever, comesup, begin to hold down a direction, until the game starts. Up will turn the ball blue, down will turn the ball green, left will turn the ballred, and right will turn it gold.
