Paper Koopa: Sticker Stashers

Paper Koopa: Sticker Stashers is the fourth installment in the Paper Koopa series. It was released on the Nintendo 3DS on December 7, 2012, making it the first game in the series to be released on a handheld console. In this game, Koopa Troopa has to gather allies to retrieve the eight Prism Stickers, which are scattered across the Koopa Island by Mario.

Unlike Paper Mario: Sticker Star, this game does not use stickers in battles as the player's only means of attack, instead only using them for puzzles. It also retains the use of RPG elements such as XP, partners, and a level-up system.

HammerBro101 saw that Paper Mario: Sticker Star was receiving flack for how much its gameplay changed, so he decided to make changes without making the game too different from previous Paper Koopa titles.
