This idea came to me when realising seasonal donuts are really, really fun to do. Considering you'll never see them (holidays) again in your gameplay, unless you want to play a gameria again... (EDIT: I apologize for saying this. I didn't realize Gamerias actually go on an infinite loop!)
There, I add all the seasonal ingredients in them and even make them look like how they are like in the cutter form thingies... like they are listed in what seasonal toppings do you get everytime.
(Constantly will be updated, it's not like I'm getting on to play Donuteria this hard everytime to get all them in time of one post)
