Does This Remind You of Anything?: When the magic bag gets stolen in "Viva Lost Wages", Felix acts as if he's lost his wife. (Complete with angst about having to sleep alone, a wallet full of romantic photos of Felix and the bag together, and the line, "I never should have taken it for granted!")
Double Take: Felix does this in "Black Magic Bag" after Roscoe flies by with his hand stuck in a knockoff magic bag and they casually say "hi" to each other.
Dream Weaver: Jeepers Creepers (a parody of Freddy Krueger). Actually, according to this universe's physics, pretty much everyone has this ability—just jump into the thought balloon of a dreaming person (or out of your own dream balloon and into theirs).
Easily Forgiven: In "Shocking Story", a worn-out lightning bolt low on power stays in Felix's house and eats all of Felix's (sentient) appliances, except for the TV, while Felix is out shopping. When Felix gets back, he simply hits the lightning bolt until it coughs everything up. Felix's TV is less than thrilled.
The Gambling Addict: Felix meets one named Billy in the Twisted Tales. Billy lost his luck because of this, since Felix is a black cat that crossed his path. Billy even begged Felix to "uncross" his path. Which Felix did. Felix, however, kept crossing Billy's path, eventually sending him to the poorhouse. Later on, Billy steals Felix's magic bag, hoping it'll restore his luck. Billy has been winning bets since then, which made him the (probably) only person who managed to steal the bag and use it. Felix eventually confronted Billy, who had a security guard throw Felix away. Felix then challenged Billy for a bet with the bag at stake. Felix then picked two dice and told Billy he could get any number he wants from them. Billy then called "13". Felix protested the biggest number he could get was "12" but Billy insisted with "13". Felix soon had an idea: he got the dot from the exclamation mark that came with the idea and added it to the six-dot face of one of the die, turning it into a seven-dot face and then threw the dice, obtaining "13". As soon as Billy lost the bag, he lost his new fortune.
Genre Savvy: As always, Felix frequently uses the surreality of his animated universe to his advantage. In one episode, he uses a remote to go back in time by rewinding the episode to a point when he could have watched a CGI version of the cartoon he's in and seen the ending, thus understanding how to get out of his difficulty. (If you had a hard time following that, you're clearly not savvy enough to inhabit this particular universe.)
Genre Throwback: The series as a whole is one big love letter after the next to classic cartoons.
Let's Meet the Meat: Just about every object in this show is animated. It doesn't seem disturbing, until one episode had Felix as a meatball deliveryman. And the meatball spoke, and had eyes, and seemed very comfortable in entering a plate full of spaghetti. Also, there's The Meat Song from "Guardian Idiot" may be the single most disturbing example of this trope ever.
Magic Skirt: In "Felix Breaks The Bank", when Candy is falling quickly, she comes to an abrupt stop for a moment, as a sudden draft up her skirt causes it to billow like a parachute. She manages to keep her skirt from rising any higher, as she looks at the camera and audience, giggles coyly and descends slowly, and safely.
Riches to Rags: The episode "Bet a Billion Bill" featured a gambler named Billy. He was wealthy and lucky until a black cat (Felix) crossed his path. In "Viva Lost Wages", Billy stole Felix's magic bag and used it as a charm to regain his fortune. Once Felix recovered the bag, it didn't take long before Billy returned to the poorhouse.
Shoddy Knockoff Product: The black magic bags mass-produced in "The Black Magic Bag". When some of the materials indentified as being part of the original bag are discovered to be very expensive, they were replaced with cheap ones under the belief the customers would never know. To replace the non-identified materials, they used cheap ones under the belief nobody cared.
Shout-Out: The episode Phoney Phelix has the Felix impostor singing a small verse of the 1950s Felix theme song.
In the same episode, in the fake Felix's flashback, one of the studios he is booted out of is called "Scumco". Also, in order to learn how to be a cartoon character, fake Felix attended an academy named Fleischer.
In a TV ad for the Fleischer school, a character is shown plummeting off a cliff, Wile E. Coyote-style.
In the two-part episode "The Fuzzy Bunny Show", Felix was mistaken for Garfield once per part.
The episode "Background Details", in which Felix and Roscoe search for a new background, is very reminiscent of "Duck Amuck".
The smiling moon used in the series strongly resembles the one in Krazy Kat.
The name of cat who kidnapped Felix and goes around impersonated as him in "Phony Phelix" is Oscar. This could be a reference to Neil Simon's "The Odd Couple". It about two opposite roommates, a neat freak named Felix and a slob named Oscar Madison. "Oscar" probably was a perfect name for a Felix the Cat impersonator to the homage of The Odd Couple.
Sidekick: In one episode, Roscoe is referred to as such to Felix.
Poindexter:(to Mr. Gleep, the Spock expy) Uh, yeah, hi. Are you from a planet where they have no emotions?
Mr. Gleep: No, I'm just a bad actor.
Thirty Minutes or It's Free: One episode had Felix charged with delivering a meatball in 5 minutes or it was free, complete with a continually running timer in the corner of the screen. When he just barely makes it in time, the customer's wife expresses her desire for a meatball of her own, and the countdown clock gives a nasty chuckle as it starts without even letting Felix get back to retrieve the meatball.
