Sore Ike! Anpanman: Anpanman to Santa-san e no Tegami

On Christmas Eve, children excitedly write letters telling Santa what they hope to receive. Melonpanna, however, cannot share their excitement; more than any present, she wishes she could spend Christmas together with her older sister Rollpanna.

Elsewhere, Baikinman schemes to take the presents for himself and soon puts the children's precious letters in danger. Anpanman and his friends must protect the messages before they are lost, while Melonpanna quietly hopes that the wish she cannot buy or wrap will somehow reach the person she misses most.
