The Cornucopia serves as the game's meta progression currency.
Cornucopias are the currency that is carried across game runs. They are primarily acquired through the Seasonal Festivals from the Mayor. If the player harvests sufficient crops during a single season, the Mayor will reward them with a certain amount of Cornucopias. Higher difficulty Years will grant more Cornucopias. In addition, Bosses will also drop Cornucopias after purchasing a certain Home Improvement from the Chemist Ant. All Cornucopias collected can be used to purchase Home Improvements and to purchase and upgrade Cats.
