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?
All these memories I thought I'd forgotten...
...كلّ هذه الذكريات التي ظننتُ أنّي نسيتُها
All diese Erinnerungen,
die ich verdrängt hatte …
Todos esos recuerdos que quiero olvidar…
Todos esos recuerdos que quiero olvidar…
Toutes ces ex
que j’avais oubliées…
Tutti quei ricordi che pensavo di aver dimenticato...
Todas as minhas memórias
que pensei ter esquecido...
О нет, я всё-всё вспомнил...
