Sore Ike! Anpanman: 12 Seiza wo Sukui Dase

A birthday celebration is being prepared at the school, and Uncle Jam has baked special bread for everyone. While the children wait for Anpanman to deliver it, Mimi-sensei teaches them about the stars and the 12 zodiac constellations visible across the changing seasons.

Baikinman, acting on Dokin-chan’s demand, steals the birthday bread and then captures the 12 constellations themselves. With the night sky robbed of its familiar signs and the party guests in danger, Anpanman must recover both the stolen food and the stars before the celebration can continue.
