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...
You're awful for totally 
forgetting about them!
Wie gemein, sie einfach zu vergessen!
C’est déplorable de les délaisser
pour faire le fou !
Sei orribile, abbandonarli così!
Que terrível você se esquecer 
dessas crianças!
