Kersti did not have a great time ever since Paper Mario Sticker Star was released: the critical bashing the game spawned had gotten into her sticker head, and she went into hiding for years after that faithful Sticker Comet mishap at the Sticker Fest in the Mushroom Kingdom.

Feeling bad for her, you decide to revisit Kersti after all these years and arrive at her sticker-adjourned home. You tug at the entrance, and surprisingly, it's unlocked. The palace-like home of hers had become a mess. And then, there she was- lounging on the sofa. However, she looked completely different than when she was last seen- she had gained a monstrous amount of weight and had a physique that the Sticker Gods themselves would disapprove of. Her belly distended so far that her crown and sticker features were hardly recognizable.

"Ugh...- What the?? HEY!!" She says as she finally notices you walking into her home, let alone without any warning at all. "What are YOU doing here?!!"
