Awesomeness Withdrawal: With only 13 episodes, some fans can't find the same kind of amusement when watching the anime shows in the Winter 2011 and beyond that they found in Ika Musume. Luckily the manga ran until Feburary 2016 for about 300 chapters.
Narm: Those dogs in the first DVD special are far more funny than they are threatening.
Narm Charm: The intentionally terrible sea puns give a lot of charm to the dub. It says something that despite the usual Subbing vs. Dubbing debates, very few fans consider the cheesy script a detractor in any way.
Nightmare Fuel: The episode "Who's The Mightiest Squid Of All". Squid Girl made several Nightmare Faces in that episode when she plots to kill them when she hears about food made of squid. Geez
Ika: I feel violated. *eyes tiny with shock/horror*
Tear Jerker: The end ofThe entirety of "Won't You Keep It?". What the hell, man.
Ika Model One! You were a real hero!
And the paper hat in the first episode. ...you know what, Ika can form a friendship with a rock and manage to make us tear up!
You had to say that! Episode 4-3, Season 2.
Let's just have a moment of silence for Ika's umbrella, alright?
Though she kinda deserves it for being so creepily obsessed, it was heartbreaking to see Sanae's increasing breakdown as she tries to give up her Ika-chan, culminating in her deleting all of her pics and burning the costumes from episode 2, while tearfully saying goodbye to her unrequited love.
The Woobie: Chizuru of all people. Even her own siblings are afraid of the sight of her with her eyes open, which leads her to stop wearing contact lenses. In Season 2 Episode 11.3 and OVA 1.2 she seems hurt by the fact that Ika and Ayumi don't think she's human.
