- Awesome Music:
- Eek's rockin' theme song.
- Release the Lawyers!
- "Can't Stop The Bugs" from OutbrEek
- The Thunderlizard's theme, as sung by Dee Snyder of Twisted Sister.
- Klutter's cheerful theme.
- The SNES game's soundtrack is surprisingly amazing and easily one of the hidden gems of the 16-bit era. The game itself is an obscure and Nintendo Hard platformer that somehow manages to have its entire gameplay revolve around Escort Missions.
- Cult Classic: Thanks to years of airing on Fox Kids, then vanishing after the Disney buyout, it's definitely this.
- Dueling Shows: Had many similarities to Garfield and Friends (see Follow the Leader): besides the talking cats, also had a similar two-story format.
- Ensemble Dark Horse: Sharky the shark dog.
- Evil Is Sexy: The evil Cat Sisters from the musical episode "Quadrapedia" were deliberately drawn in a decidedly more anthropomorphized manner than either Eek or Anabelle. Also, one of them is wearing a long evening dress highlighting her legs, while the other is Dressed Like Adominatrix.
- Family-Unfriendly Aesop: Trying to help people out will invariably get either them or you in trouble.
- Fridge Brilliance: The title of the prehistoric segment "The Terrible Thunder Lizards" is actually deeper than it looks. On the surface, it suggests that they are fearsome creatures — which, in a sense, they are, given they are giant ruthless dinosaur warriors, and in-universe they do scare the humans they're chasing. But it also has the deeper meaning that Doc, Squat and Cutter are "terrible thunder lizards" in the sense that they are terrible at being thunder lizards — which is born out by how they repeatedly fail to achieve their mission. Even the opening theme plays on this ambiguous syntax to emphasize the dual meanings, with the last lines of the song being a refrain of the phrase "they're terrible thunder lizards" — the first coming when they try to blast the humans with a bee bomb mortar, and the second coming after the humans accidentally knock the bomb back at them, so it's the dinosaurs who get hurt.
- Heartwarming Moments: Sharky and Eek hugging at the end of The Great Eekscape. Sharky is the one who actually initiates the hug. This was right around where the writers started giving Sharky more depth.
- Hilarious in Hindsight:
- In "Eek Space 9," Scully realises Mulder was right all along when an alien spaceship crashes in her office; this was during the 1995-96 season, several years before Scully's conversion became canon on the live-action show! Made even funnier by David Duchovny and Gillian Anderson voicing their characters.
- Also, General Galapagos was voiced by Kurtwood Smith- in a sense, being neighbors with Don Stark (who voiced The Rhino in Spiderman The Animated Series at the same time on Fox Kids) before That '70s Show came along (which also aired on Fox, to add to the irony).
- Jerkass Woobie: Sharky. There are episodes where he maims and attacks Eek but he gets abused more than any other character in the show. He was horribly abused in "Shark Therapy", forced into being nice in "A Sharkwork Orange" and bullied by mailmen in "The Gradueek". Most of his translated dialogue consists of sarcastic jabs at Eek or "Why me?" before he receives inevitable harm. Also, his soft, puppylike whimpers when he gets hurt will make you pity him in spite of the fact that he's a bloodthirsty guard dog.
- Just Here for Godzilla: Scooter and Bill are the best things about the Terrible Thunderlizards segments, having a classic dynamic.
- Ugly Cute: Sharky again. Also Klutter, from his segments.
- The Woobie: You have to feel bad for Sharky sometimes. Could also qualify as a Jerkass Woobie. Eek also qualifies.
YMMV / Eek! The Cat
