Paperize

Paperize is one of Kersti's abilities in Paper Mario: Sticker Star. To perform the move, she stops time and flattens the visible area on-screen, literally turning it into a picture. Mario, however, floats over the "picture", and he can choose stickers from his album to paste onto the scene. The sticker must be positioned, and after pasting it, Mario must smooth it out. He can then return to the newly altered scene. This ability is used extensively in the game to solve puzzles.

Plot
While Mario is traversing the Warm Fuzzy Plains, he encounters Bowser Jr.. To impede Mario's progress, Bowser Jr. turns a nearby bridge into a sticker and throws it onto a high ledge that Mario cannot reach. With no way forward, Mario is forced to turn back. After enlisting the help of a few Toads, Mario retrieves the bridge; however, he needs to find a way to put it back where it was. Kersti then appears, suggesting Mario use the Paperize ability. Mario pastes the bridge back where it belongs, and continues on his way.

As stated before, the ability is later used extensively in the game as a means to solve puzzles and uncover secrets. This ability could possibly be a form of breaking the fourth wall, as the area paperized is invariably the exact image seen on the Nintendo 3DS itself.
