- Catchphrase: Yeah!
- Took a Level in Jerkass: In the original comic, Mr. Blik (then Mr. Black) was - at the absolute worst - somewhat impatient and sarcastic. The show turned him into a selfish, hot-headed jerk.

- Cannot Spit It Out: When it comes to Kimberly.
- Catchphrase: Great Gopher!
- Composite Character: Arguably for the Gear version of his character and for Simon (a fourth cat who was not carried over to the show); he has the personality and coloring of the former but the eating habits and physique of the latter.
- Trademark Favorite Food: Root beer.
- Unexplained Accent: Has a Scottish accent, despite both his brothers having American accents.

- Adorkable: Waffle is a complete and utter goofball but still manages to be absolutely precious and charming in his own way.
- Berserk Button: Waffle is very vocal about his dislike of liars. While normally goofy and laid back, he will often lash out whenever he's lied to. Usually, it's directed towards Mr.Blik. He also hates cheaters.
- Catchphrase: Splee!
- Cloudcuckoolander: Considering he one time ate a meal of nothing but salt and thinks unicorns lay eggs, he qualifies.
- Crouching Moron, Hidden Badass: When Waffle has to drive Gear in a race against the Chumpy Chump Boys due to height regulations, he's at first completely useless. Then, his pet newt Gomez ends up on the Chumpy Chumps car. He then becomes a ridiculously good Drives Like Crazy driver, who can even steer with his tail.
- Genius Ditz: Waffle is much smarter than he seems. Every so often, he'll define a rarely heard word like a dictionary and can be surprisingly quick on his feet when it comes to plans.
- Friend to All Living Things: He's able to make friends with all sorts of animals except for bees and bears, it appears.

- Dreadful Musician: On the tuba.
- Not So Above It All: Hovis normally acts reasonable and clever enough, but he tends to make snarky comments whenever he finds a way to throw jabs at Mr. Blik, such as joining the fun of calling him "Mr. Pickles" when his fur turned green.

- All Girls Like Ponies: As long as they're unicorns, that is.
- Distressed Damsel: In Unicorn Club and Core-Uption.
- Friend to All Living Things: Bears notwithstanding.
- In Unicorn Club where she becomes (justifiably) angry at Gordon and even yells at him but then immediately reverts back to her cheerful self.
- In Slumber Party, she shifts back-and-forth between being exasperated with/hostile toward the cats for crashing her party and being caught up in having fun at said party.
- Nice Girl: Kind, forgiving, and looks out for the well-being of others.
