Squid Girl/Trivia
- Hey, It's That Voice! --
- In Japanese...
- In the English dub...
- Shout-Out:
- In the opening sequence there is a reference to 8-bit console RPGs, perhaps specifically the second or third Dragon Quest games. A sprite that resembles Ika disembarks from a boat, enters a cave, and opens three treasure chests (there's shrimp inside, of course). A console that looks a lot like an off-colour Sega Mega Drive/Genesis can also be seen near the end of the opening sequence.
- The first part of Episode 11 also features a pair of dolls called Johnny Depp.
- Episode 12 had "I'll be back", "I shall return" and "Yes we can!", all of them said by the MIT guys.
- In Chapter 46 of the manga, Ika Musume in her quest to become more "adult" starts watching late-night anime with Rena on the screen.
- In Episode 4.2 Eiko is teaching Ika to play Sega's Columns. In the original manga version (Chapter 27) it's one of the Gradius games.
- In Episode 10.2 Ika and Sanae are playing one of the Bare Knuckle/Streets of Rage games.
- Chizuru intervening with the Nohmen Rider stageshow as a second Nohmen Rider mirrors the originally unplanned introduction of the second Kamen Rider.
- Season 2, Episode 4.2: Ika and Eiko are seen playing Virtua Fighter on the off-colour Sega Mega Drive/Genesis mentioned above, complete with 32X-lookalike adapter.
- Season 2, Episode 5.2: One of the aliens imagined by the Three Stooges is actually "Paranoia", a boss from Space Harrier II. At this point it seems safe to assume that the makers of the anime are big old school Sega fans.
- As more confirmation of the above, Season 2, Episode 7.2 shows Ika playing Golden Axe.
- And in Episode 8.1 it's Bonanza Bros!
