Squid Girl OVA

The nefarious Squid Girl is back to continue her self-appointed mission to invade the surface world. Or that's what she would do, if she could just stop getting distracted by squidding movies, reading squidly manga, and making friends as only a squid could make them. Squid Girl must overcome not only danger found at every turn, but her own squidly good nature as well.

"Mini Ika-Musume" side-story episodes.

Foolish land-born air breathers! Behold the terror from the depths, the tentacled conqueror of humanity: Squid Girl! With your pollution and stuff you really deserve it, so prepare for menacing, inky doom! Squid Girl has come from the depths of the sea to conquer humanity for its pollution of the ocean. Within moments of arriving on the surface world, our easily distracted, little invertebrate is promptly bullied into working for the Aizawa sisters as a waitress, supplying their restaurant with squid ink. If poor Squid Girl can't handle two pushy Japanese girls, how will she ever subjugate the human race?

Bundled with the 11th and 12th volumes of the manga. The OVA adapts the manga's chapter 17 from the fourth volume, where Miia, Cerea, Mero, and Kurusu go to the gym's pool.
