Alex is disgruntled by seeing  Sanae being overly happy about Squid Girl's visit 
that day. When she finally arrives, he bites her in the leg.
Seeing that, Eiko suggests that Squid Girl takes Alex on a walk.

One morning, when Squid Girl is taking a walk on the beach, she sees kids 
gathering and moving synchronized to strange music. 
Convinced that it must be some sort of ritual or brainwashing, she can't get
the movements out of her head. 

When Gorou sees with what kind of ease Squid Girl retrieves Takeru's ball 
that was washed away by the tides, he asks her if she wants to become a 
life saver.
I can't get that squidding song from 
this morning out of my head.
Ich bekomme diese komische Melodie
 von heute morgen nicht aus dem Kopf.
No puedo sacarme esa canción de la cabeza.
No puedo sacarme esa canción de la cabeza.
Je n’arrive pas à oublier
la musique de tout à l’heure.
Não consigo tirar aquela música 
da manhã da minha cabeça.
