Sore Ike! Anpanman: Baikinman no Gyakushuu

Baikinsennin tells Baikinman about a magical vase called "Mekoisu no tsubo" that could grant him the power to destroy Anpanman. A princess of the perished Yaada-koku, Yaada-hime, also seeks the vase to restore her kingdom to its glory. When Anpanman joins forces with her, a furious chase ensues with both sides trying to get their hands on the vase. (Source: ANN)
