Ashibe-kun and Goma-chan are preparing to spend the night at Sugao-kun's house. Before they leave, Ma tells them to be on their best behavior, and they're determined to exercise good manners! Sugao-kun's dad has been doing all kinds of things to prepare for their visit, including setting up a wading pool, but his efforts seem to be in vain... Then it's time to lay out the futons and go to bed. Wait, what's that? Goma-chan seems sort of sad... Is he homesick?!

Conque las focas tampoco pueden
dormir si cambian de almohada.

non riescano a dormire su cuscini a cui non sono abituate.
Até uma foca não consegue

Значит, тюленям не спится в чужой постели?
