Soreike! Anpanman: Shabondama no Purun

A bubble performance is held by Shabondama-hime and her Shabondama Girls, who use flutes to create beautiful bubbles. Purun, one of the girls, struggles to make large bubbles despite repeated practice. She becomes upset after losing her flute and retrieving it with Creampanda's help. Meanwhile, Baikinman invades Shabondama-hime's castle and steals the flutes, using them to produce harmful bubbles. Purun must come to terms with her own value and, with assistance from Anpanman, help restore the situation.
