Before Season 4 of Cookie Run, this treasure was an A grade and only gave 8-10% XP Bonus. Sudden changes made the treasure's grade into S and boosted 11-14% XP Bonus.
During Season 4 of Cookie Run, this treasure has downgraded back to A grade with the same effect as the original S grade treasure. The image also has changed from a rainbow colored drop to a gingerbread man in a bag.
