Sticker Fest

The Sticker Fest is an annual event which is celebrated in the Mushroom Kingdom's town of Decalburg, which is the setting for the opening scene of the game Paper Mario: Sticker Star. The event, hosted by Princess Peach, welcomes the Sticker Comet which falls from the sky on the night. It is believed that the Sticker Comet is able to grant wishes. During the game's opening cut-scene, Princess Peach can be seen standing on a stage in front of a large audience. The Sticker Comet then falls from the heavens and hovers above the stage on a roped-off display. The Toads in the audience cheer in awe of the comet. Shortly afterwards, Bowser gate-crashes the celebration and takes the Sticker Comet's power, which later causes the destruction of that year's Sticker Fest. After the incident, Mario recovers and soon meets Kersti, a powerful Sticker who came from the Sticker Star to grant everyone's wishes at the Sticker Fest. She wishes Mario to help her recover the Royal Stickers, which were split from the Sticker Comet during the Sticker Fest.
