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?
