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...
Parents and child, always together 
and always getting along!
Eltern und Kind verstehen sich
 gut und sind immer zusammen!
Siempre juntos, una familia unida.
Siempre juntos, una familia unida.
Toujours unie
et sur la même longueur d’onde !
Sempre uniti, sempre affiatati, genitori e figlio!
Pais e filhos sempre juntos e sempre se dão bem!
