In order to use Flip, the player must simply press the 1 button on the Wii Remote. With this ability, Mario can flip into 3D which is required to solve puzzles in certain areas. This ability can also be used to help defeat enemies and bosses. However, Mario cannot stay in the 3D world too long as a meter shows up on the screen. If the meter gets empty, then Mario will slowly start to take damage along long he remains in the 3D world. However, if Mario completes the Flipside Pit of 100 Trials and defeats Wracktail, he will earn a special power that allows him to stay in the 3D world for as long as he wants without worrying about taking damage.
