The girls in the Breakwater Club learn how to float properly just in case they ever fall into the ocean. Later on, Hina goes to battle with a heron, but then notices it has a fishing line tangled around its leg.
But if I can't see the bottom
like deep in the ocean, no way.
لكن إذا لم أتمكن من رؤية القاع، كأعماق المحيطات، فمن 
!المستحيل أن أسبح عندها
Pero si no puedo ver el fondo
como en el océano, no hay forma.
Par contre, j’ai peur de la mer,
on ne voit pas le fond…
Mas se eu não puder ver o
fundo do mar, não tem jeito.
