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.
