How much is that squiddy in the window?
Ika Musume discovers a wallet on the beach and is awarded 10,000 Yen for returning it to its owner. However, she doesn't quite understand the value of money, so she goes on a small shopping trip with Nagisa. Ika Musume ends up blowing the money on a large batch of shrimp while Sanae watches from afar. Later, after eating all the shrimp back at the Lemon snack shop, Ika finds out that 10,000 could have covered the cost of repairing the wall she broke. Also, Sanae sends Ika a giant package, which turns out to be herself in a giant shrimp suit.
Ride 'em, Squiddy!
Ika Musume wants to follow the Aizawas back home, but Eiko wont let her, so she tries to make her own fun at the Lemon after closing. However, the TV breaks, so Chizuru decides to let her into their house. After the family goes to sleep, Ika tries to play with Eiko, but somehow manages to crawl into her bed instead and tangle up Eiko in her tentacles the next morning.
You're phonier than an 11-tentacled squid!
A lot more kids on the beach seem to be amazed by Ika Musume, and Eiko hears that someone on a neighboring beach has built a fake Ika-Musume, so the two of them go to investigate. They discover a man who has built a Squid Girl head and put it on the body of a woman in a bikini, but the fake head can squirt ink and move its tentacles just like Ika Musume, so the man and Eiko decide to have a contest: whichever Squid Girl can serve the most customers at the Lemon wins.
