This episode of Meisaku is inspired by a nursery rhyme, "The Rolling Acorn." Musubi tries to beat a rolling acorn, tumbles, and falls into a pond. There, he meets...a loach? Musubi is voiced by Manabu Kaneko of Ushiro City.
I'll shout "There!" when you get to it,
 so start singing, Meisaku.
Wenn du bei diesem Teil bist,
geb ich dir Bescheid!
Te detendré en la parte molesta.
Canta la canción, Meisaku.
Te pararé en la parte molesta.
Canta la canción, Meisaku.
Je dirai « voilà ! » quand on y sera.
Chante, Meisaku.
Dirò "Ecco!" quando arriva,
perciò comincia a cantare, Meisaku!
Eu grito quando chegar a parte ruim.
 Pode começar a cantar, Meisaku.
