- Accidental Innuendo:
- "What's Cooking with Theo and Cleo" features a lot of rhyming titles like "Slammed and Rammed Ham", "Squished Fish in a Dish", "Beef in a Sheet", and "Tackled and Paddled Hamburger". Considering the two openly flirt on the show and sometimes seem to be close to killing the Y-rating, it could be intentional.
- Arty Smartypants: Puts stuff into his pants, does a dance that comes across as... twerking.. This is accompanied with the line mentioned below, under Ear Worm, which adds to the awkwardness.
- Awesome Music:
- "Pygmalion's Song: in the episode "Hug, Hug, Hug!"note , if you're into Power Ballad love songs.
- Click's song from "Little Big Mouse". It will make you feel for a computer mouse.
- The closing song from "Shooting Stars" is rather good, too.
- Anything by the Monkey Pop-Up Theater. Doubles as an Ear Worm.
- Big-Lipped Alligator Moment: The "We Choose to Cha-Cha-Cha" song Theo and Cleo sing in the episode "The Chap with Caps." They are simply enjoying their job as librarians, and then randomly break out into the song for no reason, and once finished, they resume what they were doing as if nothing happened.
- Ear Worm:
- The theme song. C'mon, you can't tell us that theme song hasn't gotten stuck in your head at least once!
- "Cliff Hanger! Hanging From a cliff! And that's why he's called Cliff Hanger!"
- "Ooh! Aah! Dance in smarty pants!"
- "Grow, mane, grow, mane, make it grow! Grow, mane, longer, go, go, go!
- "Meat shower, meat shower, meat shower!"
- If You Can Read At.
- Ensemble Darkhorse: Click
- Fridge Horror: During "Silent E", we see the titular villain turn a twin into a twine. When one stops to realize he turned an innocent kid into an inanimate object, it's suddenly a lot less amusing and cements Silent E as the monster he's portrayed as.
- Heartwarming Moments:
Oh, and Sometimes YY, don't you cryYou're not a fulltime vowel,but don't throw in the towel,My little sometimes Y.
- Some of the lyrics to Sometimes Y were pretty sweet.
- The entire cast singing "A Sad Book" at the end of "A King and His Hawk."
- Memetic Mutation: Cliff Hanger's "Can't.... hold... on... much... longer!" line is quoted quite a bit.
- Nightmare Fuel:
- Retroactive Recognition: Look up Peter Linz, the voice of Theo. You'll find that he's Tutter from Bear in the Big Blue House and The Muppets's Walter!
- Seasonal Rot: Happened around season 5. This season and beyond were radically different from the earlier seasons, focusing on consonants rather than vowels and showing two fifteen-minute episodes at a time instead of one thirty-minute episode. Worse, Cliff Hanger got dramatically flanderized and other fan favourites such as Click, Heath, and Busterfield were retired for no good reason.
- Signature Song: "Cliff Hanger," "Sven Said Ten Tents," "Rocket-Doodle-Doo," "Silent E," "Grubby Pup," "Sloppy Pop," "If You Can Read AT," "When Two Vowels Go Walking," "Dance in Smarty Pants," "Get Your Mouth Moving," "Ten Little Words," or "Grow, Mane, Grow!"
- Tear Jerker: The entirety of "A King and His Hawk", both in-universe and out-of-universe. About half of the episode consists of crying.
- Leona receiving "The Gingerbread Man" as a birthday gift, only to be heartbroken when the story ends with him being eaten. Part of the party ends up playing out like a funeral in the gingerbread man's memory, with the lions even singing a song to say goodbye to him. Silly as the whole thing is, it evokes the very real pain that is characteristic of such a moment.
- Uncanny Valley:
- Arty Smartypants. That one messed-up eye and that the other one is cold, dead, unblinking and fixed on the viewer is already a bit unnerving, but his overall strange anatomy and his human hands can make his appearance downright harrowing to some viewers.
- Heath the Thesaurus might also count. It's not so bad when we just see his head and neck, but when they show his whole body, he's downright creepy.
- The Woobie: Chicken Jane. Also, Cliff Hanger, at least pre-flanderization.
