As part of the channel's focus on Cartoon Network's "classic" programming, the videos moved to air during commercial breaks on Boomerang in the late 2000s and early 2010s. You can view many of them here
and here.
Some (but not all) of the original Cartoon Network Groovies made were:
- 24th Century Mecha-Mix by Michael Kohler (The Jetsons)
- Back to the Lab by Prince Paul note (Dexter's Laboratory)

- Chemical X by Cherish (The Powerpuff Girls)
- Circles by Soul Coughing (various Hanna-Barbera cartoons), a Deconstructive Parody of the Wraparound Background trope.

- Signal in the Sky (Let's Go!) by The Apples in Stereo (The Powerpuff Girls)
- That Time is Now by Michael Kohler (Superfriends)

- When It's Over by Sugar Ray (depicting the band In the Style of various toons, including The Jetsons and George of the Jungle)
- Yogi Bear Live at Yellowstone by High School Jim note (Yogi Bear)
Some of them originally started out as Shorties, including:
- Atom's Theme (The Atom Ant Show)
- El Kabong Rides Again by Calexico (Quick Draw McGraw)
- Jabberjaw (Running Underwater) by Pain (Jabberjaw), showing the Neptunes as a ska band playing on a vintage metal Jabberjaw lunch box and rescuing Shelly from an eel who falls for her during a performance.
- Musical Evolution by Christina Fincher note (Josie and the Pussycats), showing the Josie and the Pussycats theme as a disco tune, a late 1970s punk anthem, a country ballad, a KISS-style arena rock song, and as a techno/house beat.
Cartoon Network Groovies contains examples of:
- '70s Hair: When the music in Musical Evolution turns to 1970s disco, Valerie suddenly begins sporting a huge afro even bigger than her actual '70s afro.
- Adaptational Attractiveness: Eustace and Muriel are drawn to look a bit younger in Courage (Hearts Full of Love).
- Adaptational Badass: In El Kabong Rides Again, Quick Draw McGraw is depicted as a way more effective crime-fighter than the Idiot Hero that he is in his original shorts, defeating the main villain and saving the townspeople twice over with little issue and even getting the girl in the end. Conversely, Baba Looey has to be rescued by Quick Draw twice.
- Animesque: Dee Dee and Dexter resembles a 1960s anime and even features the Japanese language.
- Art Shift: Musical Evolution gives each version of the Josie and the Pussycats theme its own art style.
- Bat Signal: "Signal in the Sky" is about the Powerpuffs having such a signal.
- Chained to a Railway: The villain in El Kabong Rides Again takes this to the extreme by not just tying up Baba Looey and the Damsel in Distress, but all the townspeople as well. El Kabong saves them by using a gigantic metal guitar to destroy the incoming train.
- Crappy Carnival: Courage the Cowardly Dog takes place in one themed on the show, with the aptly named title "Courage's Night Terrors". The carnival itself doesn't look too bad, but it's dead empty, uncannily bright, and has attractions based on the horrors the titular character faces.
- Deliberate VHS Quality: My Best Friend Plank has the nostalgic grainy look of an old home movie.
- Delinquent Hair: '90s punk Josie and Melody wear mohawks.
- Enemy Rising Behind: During Signal in the Sky, the Apples are singing the song in a tall building while the Giant Pufferfish Balloon is trying to jump up to their window without success until he uses a smaller building as a stepladder. While the rest of the band notice the monster coming up to them, the lead singer keeps going until its fin breaks through the window.
- Failure Is the Only Option: Gorilla 4 Sale is all about Mr. Peebles' inability to just sell off Magilla. Most verses talk about almost sales that are only inhibited by circumstance.
- Funny Background Event: In Musical Evolution, Valerie and Melody give confused looks everytime they switch up.
- Hall of Mirrors: In Time is Running Out, Bandit finds himself in a hall of mirrors and threatened by a gargoyle. He barks loud enough to shatter the mirrors one by one, and when he barks at the real gargoyle, it cowers and lets him pass.
- Hope Spot: The final verse of Gorilla 4 Sale details the one customer willing to buy Magilla Gorilla, a little girl named Ogee. She's enthusiastic and seems to love the gorilla...but right at the end she sadly mentions she doesn't have enough money to claim him. "Mr. Peebles almost died" indeed.
- Horsemen of the Apocalypse: Atom's Theme has Atom fighting off four otherworldly men riding on horses. War is represented by a general with a tank, Famine by a three-headed man extolling the virtues of nuclear fire, Pestilence by a giant scrap robot breathing fire on the town, and Death by a robber planting nuclear Cartoon Bombs all over the world.
- Medium Awareness: The plot of Circles concerns Fred and Barney becoming aware of the Wraparound Background.
- Relocating the Explosion: In Atom's Theme, Atom Ant carries all the nuclear bombs into space so they can detonate safely.
- Retraux:
- The Musical Evolution short uses this as it goes through different music styles.
- Dee Dee and Dexter is styled like a 1960s anime.
- Setting Update: Josie and the Pussycats gets updated for the '80s and '90s, complete with changing music styles.
- The Shadow Knows: Eustace might have been redesigned in Hearts Full of Love, but his shadow has his regular show design.
- Shout-Out: Josie and the Pussycats dress up like KISS members at one point in their Groovie.
- Stop Motion: Time is Running Out is animated with very convincing figures made for the short's board game aesthetic.
- Tarot Motifs: Briefly shows up in "Courage the Cowardly Dog". While Muriel's card ("The Kind") is not a real card, Eustace's card ("The Fool") is.
- Unnaturally Looping Location: Barney's house in Circles, which somehow even warps in characters from other universes.
- Visual Pun: The first Horseman of the Apocalypse in "Atom's Theme" is depicted as a three-headed salesman whose Coat Full of Contraband is filled with smiley faces. He's quite literally "selling smiles" (lying that everything is okay when it's not).
- Wacky Racing: Rolling's video takes clips from the Betty Boop episode Betty Boop's Ker-choo in which she, Koko, Bimbo, and a few others compete for a racing trophy.
