Just an idea here , what if there's a booth / house selling food just like how destiny sold their hats -" stock system" . Like this we can ensure the rarity of some food and make the collections of food rarer . The difference is that the shop stop selling a type of food after that period instead of bringing it back like the destiny hat . Also, this will increase the number of people visiting snow town . Perhaps bring more competition to snow tower as people start Pk ing there while waiting etc.
