The stage this time is Baquel Carnival! It's a fun festival held in Obake Town, a cute and fun city of ghosts that can be transformed into anything! Children truly enjoy the amusement park-like glamorous and exciting Baker Carnival. However, only the ghost boy Dolorin, who is not good at transforming, can not enjoy it, so he is alone. Such Dolorin deepens the bond while encountering Creampanda. They head to Ozomashi no Mori in search of the cloak that has the most transformational power in the world, but Baikinman appears there and rampages to mess up the Baker Carnival with the power of the cloak! Can Anpanman and others protect the fun Baker Carnival from Baikinman?
