Ashibe and his friends are visiting the location where Yuma-kun's mom is shooting a drama, and Omata Tamao-chan has a role as a lifeguard in a beach scene! But then they find out that Tamao-chan can't swim. The director is ready to have Yuma-kun appear in her place... but Tamao-chan can't have that, so she has Goma-chan teach her how to swim!
There's no point in a 
lifeguard who can't swim.
لا جدوى من مُنقذ لا يجيد السّباحة
Eine Lebensretterin,
die nicht schwimmen kann, bringt’s nicht.
Una salvavidas que no sabe
nadar no sirve de nada.
Una salvavidas que no sabe
nadar no sirve de nada.
Une maître-nageuse qui sait pas nager,
on est dans de beaux draps.
Una guardaspiaggia che
non sa nuotare non serve a nulla.
Se a salva-vidas não sabe
nadar, não há o que fazer.
Зачем нужен спасатель, 
который не умеет плавать?
