Won't You Go to Elementary School!?
Takeru is starting school again, and Ika-chan wants to come along, saying Chizuru has been telling her she should start elementary school. Ika-chan underestimates the sheer amount of kids at school and how much they like playing with Ika's tentacles. Unfortunately, the teacher, who was looking forward to her students greeting her again, is promptly ignored by the kids and Ika-chan.
With the teacher out of the way, Ika-chan takes the opportunity to tell the class how terrible humans are for polluting the ocean, and rallies them all for her cause to take back the clean ocean. Unfortunately as she is parading onto the soccer field, she gets into an argument with a few 5th grade students playing on the soccer field that almost run her over. She then challenges them to a soccer match.
Great kick Ika-chan! (Not really)
Unfortunately, Ika-chan is terribly uncoordinated with using her legs to kick the ball. Eventually the 5th graders realize that Ika-chan has a lot of supporters, and that if they won they would probably look like jerks for not letting her use her tentacles and all. So they make a secret agreement with the kids in Takeru's class to rig the game so that Ika-chan scores a goal. The match ends in a draw. Ika-chan is very satisfied with herself and the 5th graders agree to share the field with her.
Just as Ika-chan is reveling in her triumph, the teacher appears and wins over the students with free ice cream, leaving Ika-chan back where she started.
Won't You Cosplay!?
Eiko and Chizuru begin to realize that the Lemon has very few female customers. Chizuru determines that if they had a hot male waiter, there would be more female customers. Somehow they force Nagisa to cosplay as a young attractive male waiter, which starts racking in the female customers. Upon seeing this, Ika-chan tries to scare Nagisa and reveal her true colors to the female customers, but she isn't successful as Nagisa is doing a good job playing the cool and collected Mr. Nagisa.
Then Chizuru and Eiko begin to wonder how they are going to re-attract all the male customers again. Then, Ayumi and Ayumi's father drop by. Her father lets Ayumi work at the Lemon in the hopes that Ayumi will be less shy in a place where she is less known. Eiko and Chizuru have her wear a maid outfit, and Chizuru gives her a spiky brass knuckle to wear to help counter her shyness. It seems to do the trick as a male customer is forced to think twice about hitting on Ayumi.
Ika tries to be a Queen
With Chizuru and Ayumi gaining confidence in their new personas and attending to customers with new confidence and energy, Ika-chan is being left in the dust. Ika-chan is worried that this will ruin her ability to use the Lemon as her home base for invasion. Then Ayumi's father comes around to see how Ayumi is doing, Ayumi scolds her saying, "You fool! this isn't any different than the robotic squid costume!" and takes her back with him. Nagisa also realizes that she hasn't really changed herself either, and is just hiding behind a fake persona. Ika-chan tries her hand at cosplay too, playing as Queen Squidizabeth, but it fails miserably.
Squidn't You Lose a Little Weight!?
"The scale was mistaken!" - Chizuru
It's an extremely hot day at the beach. Sanae who is almost about to die from dehydration stops by to drink a glass of water. It turns out she was on a diet, and she was exercising on the beach wearing a sweatsuit. Ika-chan tries to get an understanding of what this dieting business is all the fuss about, Sanae explains excitedly the concept of dieting. Eiko is more carefree about her weight. Chizuru listens in and seems irritated. They decide to weigh Ika-chan (since she looks so skinny, but is so strong with her tentacles), she turns out to be 100kg. Chizuru tries telling them that the scale is broken and ends up breaking the scale in anger, but she tries to cover it up by laughing. Eiko wonders why Chizuru lied about the scale.
Then at home Chizuru weighs herself again and is anxious, but tries reassuring herself since Ika-chan is 100kg and is still so skinny. Ika-chan weighs herself on the new scale and is now, somehow 30kg. Ika-chan explains that she can change her weight by turning her bracelet. This is so that she can do heavy lifting and such with her tentacles, and then the weight of whatever she is carrying won't cause her body to fall over.
Ika can fly! Oh gosh a falcon!
With this revelation, Ika-chan realizes that she can make herself so light that she should be able to fly. So she tries taking off of the roof and starts gliding in the sky. But she is picked up by a hawk and almost turns into bird food. It seems that just as she can't conquer anything on land or sea, the sky is no different.
