A fight breaks out between Squid Girl and Eiko and this time things aren’t patching up as quickly.  With the tension in the air Chizuru closes the restaurant early so the group can go to the local Festival.  Will Squid Girl go back to the sea or will a mysterious visitor be the key.
I'm not the one who dumped 
the mop on your head.
Ich war's nicht, der dir den Mopp übergebraten hat!
Yo no soy la que soltó un 
trapeador sobre tu cabeza.
Yo no soy la que ha soltado 
una fregona sobre tu cabeza.
Ce n’est pas moi qui t’ai mis
ce balai sur la tête.
Não é minha culpa que o esfregão
 caiu na sua cabeça.
