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?
It seemed like he didn't 
understand what I was saying.
بدا وكأنّه لم يفهم ماذا كنتُ أقول
Es sah so aus,
als hätte er mich nicht verstanden.
Sembrava non capire quello che gli stavo dicendo.
Parece que ela não
entendeu o que eu disse.
Гома перестал меня понимать.
