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.
If you fall in, don't panic.
.لا تهلعن إذا وقعتن
Ihr dürft nicht in Panik geraten,
Si se caen, no entren en pánico.
Il ne faut pas paniquer en tombant,
Se você cair, não entre em pânico.
