10-Point Star

A 10-Point Star (originally parsed as 10 Point Star) is a Special Item that a Yoshi can collect in Super Mario World 2: Yoshi's Island and its reissue, Yoshi's Island: Super Mario Advance 3. It can be obtained by winning certain minigames. It is worth 10 Stars, giving him 10 more seconds for the Countdown Timer. There is a similar Special Item called a 20-Point Star.
