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.
If you play a game with me, 
I'll take you to the shore.
Wenn du mit mir ein Spiel spielst,
bring ich dich ans Ufer.
Si juegas conmigo,
te llevaré a la orilla.
Si juegas conmigo,
te llevaré a la orilla.
Si tu joues avec moi,
je t’y emmènerai.
Se giochi con me, dopo ti porto a riva.
Se você jogar um jogo comigo,
 eu o levo até a margem.
