Squidn't That English?! / Ink You Can Stop It?! / Get My Drift?!
After Takeru has trouble understanding a tourist, Cindy holds an English-teaching session, with Eiko being the only one who doesn't understand anything. This leads to some communication errors as Cindy misinterprets Eiko's Japanese as English. Later, Squid Girl learns about tickling from Eiko and starts going around tickling others. However, she gets her comeuppance when she attempts to tickle Chizuru and ends up catching hiccups, which she believes can only be cured if something makes her happy. Later, Squid Girl joins Takeru and the others by the river, where they have a race with grass boats. As Squid Girl follows her boat down the river, she winds up on a completely different beach.

Squid Girl 2
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.
