What if there were some sort of system in the game where you could try to change the color of a costume/accessory in a similar way to how Punch's UV rolling works? It wouldn't change whatever kind of item it is (a ribbon will stay a ribbon), but the color type would change in a random way (toasty could become military or regal or prismatic or whatever).
Usually this happens when theres an even take the Iron Wolf Costume and the Gold Wolf they are both things people wanted and the majority of events have colored costumes like Valentines Day, Halloween, and Winterfest.
