As Goma-chan is swimming in the river, a shark's silhouette appears behind him?! The shark turns out to be Dot-chan, a young whale shark that escaped from the local aquarium! Goma-chan and Dot-chan quickly become great friends and have fun swimming in Dot-chan's tank at the aquarium together. But when Ashibe-kun calls out to Goma-chan that it's time to go home, Goma-chan doesn't seem to understand him... What's happened to Goma-chan?
I didn't understand anything 
he was saying, either.

Yo tampoco entendí lo que dijo él.
Yo tampoco entendí lo que dijo él.
Moi non plus,
je n’arrivais pas à saisir.
Nemmeno io capivo quello che mi stava dicendo.
Да я и сам не понял, что он мне ответил.
