Princess Peach stands behind a large cake, and the player must quickly decorate it before time runs out. The screen is filled with floating toppings like strawberries, sprinkles, whipped cream, and chocolate drizzle, each appearing in a bouncy, colorful pixel-art style. A Toad judge on the side reacts based on how well the cake is decorated, with a rating meter flashing between "Sweet!" and "Oops!"
