それいけ! アンパンマン いのちの星のドーリィ

The annual Star Festival to honor the stars that bring life is drawing nearer. Anpanman finds an abandoned doll who is brought to life by a Star of Life. The doll, now named Dolly, spends all of her time having fun, convinced that enjoying oneself is the meaning of life. However, her Star of Life is starting to disappear, and Baikinman builds a huge robot inspired by memories of his own birth.
