The ability in Super Paper Mario that lets Mario flip between 2D and 3D is called Flip. It allows Mario to shift between the game’s flat side-scrolling view and a three-dimensional perspective, revealing paths, objects, and secrets hidden in the other dimension.
Flip is the central mechanic that distinguishes Super Paper Mario from earlier entries in the series. In 2D, Mario navigates traditional platforming spaces; in 3D, he can move around the apparent depth of the environment and uncover alternate routes. The ability is introduced early in the adventure and becomes essential for solving puzzles and reaching new areas.
The terms Warp, Switch, and Turn describe plausible actions but are not the name of this mechanic. Flip is also separate from the Pixls’ special abilities, which provide other ways to interact with enemies and the environment. The game’s main hub, Flipside, takes its name from this dimension-shifting concept.
