Secret Strike

In Bowling, during a 100-Pin Game, move your character all the way to the left or right (by using left or right on the d-pad), and roll a ball all the way down the gutter guard without it falling off. If it works, there will be a muted explosion sound, and all the pins will miraculously fall over. After completing the match you get the Secret Strike stamp.
