Soreike! Anpanman: Baikinmans Counterattack, それいけ! アンパンマン ばいきんまんの逆襲, Soreike! Anpanman: Baikinman's Counterattack

Baikinman was informed by Baikinsennin about a mystical container known as "Mekoisu no tsubo," which could grant him the ability to annihilate Anpanman. Additionally, Yaada-hime, the princess of the defunct Yaada-koku kingdom, also seeks the vase in order to restore her realm's splendor. When Anpanman teams up with her, a heated pursuit ensues as both parties strive to acquire the vase.
