Tamako works at her father's mochi shop, and along with her friends she enjoys a comfortable life at Tama-ya, the local shopping district. A talking bird suddenly interrupts their little slice of paradise, and things begin going downhill from there. As New Year's Eve arrives, with Dela having put on weight after gaining an affection for mochi, Dela almost chokes on a mochi, prompting the neighbourhood to help him out, overlooking Tamako's birthday.
