ALT In Paper Mario: Sticker Star, Kersti appears to be roughly equivalent in value to a Worn-Out Jump sticker, one of the worst stickers in the entire game. The game contains hidden "Paperization Blocks", spots where stickers can be stuck in order to be upgraded to better stickers. If cheats are used to take Kersti's sticker form out of a final boss battle and upgrade her, she will always turn into a regular Jump sticker. The only stickers that have a chance of turning into regular Jumps when upgraded are the Worn-Out Jump and, rarely, the regular Hammer stickers. Together with the fact that Kersti sells at shops for the low amount of 15 coins, this suggests the developers could have deliberately programmed her to have low value as a joke.
