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.
Are you that bad?
هل أنت سيّئ لتلك الدرجة؟
Bist du so schlecht?
T’es mauvais à ce point ?
Sei davvero così terribile?
Você é tão ruim assim?
Что, так плохо поёшь?
