This episode of Meisaku is inspired by "Urashima Taro" from the children's song. Bolt can not sing the song "Urashima Taro" to the end. An "Utashima Taro" appears and tries to teach him the correct lyrics...and fails.

Utashima Taro is voiced by Yuyu-uta, a YouTuber.
My terrible singing is getting me down.
.غنائي الفظيع يؤثّر على نفسيتي
Ich bin traurig,
weil ich nicht gut singen kann.
Qu’y a-t-il ?
Non riesco a cantare. Sono terribile.
Estou chateado porque eu canto muito mal.
Расстроился, что не могу 
нормально петь.
