There are plenty of fish in the sea, but not one quite like Taiyaki-kun.

The reissued version of Japan's best-selling record of all time, "Oyoge! Taiyaki-kun" ("Swim! Taiyaki"), has reached No. 22 on Oricon Inc.'s top-50 hit chart, and more than 30,000 copies have been sold since the new version debuted this month.

It's the first time the fish snack tune has made the top 50 since June 1976.
