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.
 He felt helpless and opened the box
 شعر باليأس فقام بفتح الصندوق
Er fühlte sich einsam
und öffnete das Kästchen.
Desesperado, abrió la caja
Desesperado, abrió la caja
Quand de déprime il fut pris,
la belle boîte il ouvrit
Preso dalla disperazione aprì la scatola
Chateado, a tampa ele resolveu desprender
В отчаянии он открыл шкатулку.
