Nicknames: "They Ripped Off Golden Book Video and KC and the Sunshine Band!", "Rainbow KC"
Logo: On a black, starry background, a cherry-red text "Klasky" moves from the top while a grape-violet "CSUPO" moves from the bottom. Suddenly, an exploding supernova appears in the center, and form the initials "KC" in rainbow stripes. A creamy yellow text "An Arlene Klasky & Gabor Csupo Production" in the Balloon font appears below.
Variant: Since the fifth episode of The House of Spooks, the text below the KC logo reads "A Klasky-Csupo, Inc. Production". Also, the logo fades out after 15 seconds.
Cheesy Factor: The starry background looks obviously fake, the explosion looks and sounds like a 1985 Golden Book Video logo, the KC logo looks too similar to the logo for the funk group KC and the Sunshine Band, and the rainbow stripes are colored like the original Life Savers candy, but with purple and slightly darker. Also, the first note of the music sounds like it came from a creepy 70s Moog synthesizer. This could also be one of the longest closing logos in the history of television, lasting about 30 seconds.
FX/SFX: Really cheap animation.
Music/Sounds: A long "wah" note played in a synthesizer, the loud explosion (recycled from the Golden Book Video logo), and an 80s Hi-NRG disco beat. ("Mama Told Me" by Fantastique)
Availability: Extremely rare; the original 30-second version was shown on the the original pilot episodes of Ickis and Oblinafrom 1986. The 15-second variant was also shown on The House of Spooks, but on recent reruns, this logo was removed.
Scare Factor: Medium to NIGHTMARE! The explosion may scare some people and the colors of the rainbow stripes in "KC" look kind of gross.
Logo: On a lavender-blue background with shapes, we see a still picture of Ickis from The Ickis & Oblina Show. Next to him is a text which reads " A Production of Klasky-Csupo, Inc."
- In a few shows, the logo shines and stars appear in the background.
- Sometimes a byline appears below the logo which reads "IN ASSOCIATION WITH . . . " in a Dom Casual font with a black shadow.
Music/Sounds: None, or the closing theme of the show, but on a few occasions, the music is borrowed from the Rugrats title card.
Availability: Seen on a few shows that K-C made before Rugrats except for The Simpsons, The Tracey Ullman Show, and the HBO special Alexander and the Terrible, Horrible, No Good, Very Bad Day. Also shown up at the start of the pilot of Rugrats, "Tommy Pickles and the Great White Thing", but the Nickelodeon Haystack is shown at the end of the pilot.
Scare Factor: None to Low.
