After blowing out the candles on their cake, the player will be given a stick and a piñata set up for them to beat. The piñata contains Birthday Cupcakes; the faster the player hits it, the more cupcakes there will be. The player is then given an item from the Birthday Set and can enjoy the party until they leave the house, after which it returns to normal. When the player exits their house after the party, they will receive a Homemade Cake from Mom in the mail. Additionally, a Nook Miles Stamp called "Happy Birthday" will be unlocked.
