Today's lesson is at the school's pool. Yokoi-san takes it very seriously, while Seki-kun messes around with his friends... and it appears that some familiar robots are back...
For crying out loud... 
How did you get them in?
Oh Mann... 
Wie hast du die hier rein gebracht?
Rayos... ¿Cómo logró traerlos?
Jopé... ¿Cómo se le ha ocurrido traerlos?
Vraiment…
Comment a-t-il rapporté ça ici ?
Che cavolo... 
Come hai potuto portarli qui?
Fala sério...
 Como você os trouxe para cá?
