Royal Sticker

The Royal Stickers are special stickers from the Sticker Comet that can grant wishes and give power that appear in Paper Mario: Sticker Star. Kersti is their guardian, as they all live together on the Sticker Comet. On the night of the Sticker Fest, Bowser touched the Sticker Comet and scattered the Royal Stickers across the lands. Mario and Kersti travel to five lands to reclaim the stickers: the grasslands of World 1, the sunbaked desert of World 2, the dark woods of World 3, the snowy mountain of World 4, and the volcanic island of World 5, battling Bowser's minions to save the five Royal Stickers. The final and most powerful sticker lands on Bowser's head and grants him amazing power.

Royal Stickers have the power to alter the personalities of many creatures, most noticeably the game's bosses. Once a boss is defeated, there is a rhyming story telling how each boss got the sticker and the background before they received it.

Trivia

 * The orange Royal Sticker (or at least a look alike) makes a minor appearance in Mario & Luigi: Paper Jam during the fight with a Big Pokey and the Tower Power Pokey, where it can be seen worn once again by the Tower Power Pokey. It doesn't have anything to do with the plot and Mario and Luigi and Paper Mario do not take the royal sticker after the battle. The orange gem on top of the Royal Sticker has been replaced by an orange spike.
 * The final Royal Sticker also appears on a Battle Card, being worn by Shiny Paper Bowser.
 * The red Royal Sticker's likeness is used in the design of the Megacrinkle Goomba Papercraft, which seems to have been designed after the similarly named Megasparkle Goomba.
