Ep 4. How much is that squiddy in the window? / Ride 'em, Squiddy! / You're phonier than an 11-tentacled squid!

Squid Girl season 1 episode 4 is composed of three short stories. The first segment called "How much is that squiddy in the window?" features Squid Girl's visit to a pet shop, where she gets distracted by the adorable animals. She tries on hats and sunglasses, which make her look cuter and easily catches the attention of the shopkeeper. When a customer comes to buy a squid, Squid Girl tries to convince them not to since she is a cephalopod herself. The customer, however, assumes that she is just a girl in a squid costume, which backfires on Squid Girl.

In the second segment called "Ride 'em, Squiddy!" Chizuru takes Squid Girl out for a ride on a bicycle. Initially, Squid Girl is hesitant as she has never ridden a bike before. As they make their way to the beach, Squid Girl enjoys the experience and starts racing with Chizuru. Soon they end up competing with two other girls who are also riding bicycles. In the end, Squid Girl's tentacles grow tired, ending the race abruptly.

In the final segment, "You're phonier than an 11-tentacled squid!" Squid Girl's actions come under scrutiny when she tries to deny being a squid and instead claims to be a human who is cosplaying as a cephalopod. Her attempts to prove that she is human by eating several sweet snacks backfires as the tests she experiments on herself to prove she is human show her to be not human.

Overall, Squid Girl season 1 episode 4 is a fun collection of three short stories that highlight Squid Girl's naivety and curiosity. The first segment showcases Squid Girl's playful nature, while the second segment delves into her adventurous side. The final segment highlights Squid Girl's innocence and her struggle to understand the human world. The episode is a must-watch for those who love lighthearted and comedic anime series with fantastic animation and lovable characters.
