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

Cartoon Network Groovies contains examples of:
- '70s Hair: When the music 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.
- Art Shift: Musical Evolution gives each version of the Josie and the Pussycats theme its own art style.
- Animesque: Dee Dee and Dexter resembles a 1960s anime and even features Japanese.
- Bat Signal: "Signal in the Sky" is about the Powerpuffs having such a signal.
- 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.
- Damsel in Distress: Shelly in "Jabberjaw" is kidnapped by the evil eel.
- 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.
- 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.
- The Four 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.
- 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.
- Medium Awareness: The plot of Circles concerns Fred and Barney becoming aware of the Wraparound Background.
- 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:
- The characters of Jabberjaw are updated from 1970s teens to late 1990s/early 2000s teens. More specifically, they're a part of a ska band.
- 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:
- Stop Motion: Time is Running Out is animated with very convincing figures made for the short's board game aesthetic.
- Unnaturally Looping Location: Barney's house in Circles, which somehow even warps in characters from other universes.
- 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.
