Nicktoons Originals

Background
Nicktoons TV was launched by Nickelodeon in 2002 as a channel for their entire cartoon library, consisting mainly of archived ones (such as Ren and Stimpy, Doug, etc.). In 2003, the channel was rebranded as Nicktoons before being renamed to Nicktoons Network in 2005 and back to the former name in 2009.

1st Logo (October 24, 2004-2005)
Nicknames: “Nicktoons!!”, “Boomerang splat”

Logo: It utilizes the 2004 Nicktoons logo, saying "NICKTOONS", as it rotates in thin air like a boomerang until it splats on a gold light wall, ending with a guy shouting “Nicktoons!”

FX/SFX: Whoosh! Splat!

Music/Sounds: The end of the 2004-2005 Nicktoons Film Festival theme song can be heard, while a guy shouts “Nicktoons!”

Availability: Extremely rare. Extinct. Shown only at the Nicktoons Film Festival in 2004, and the Nextoons Nicktoons Film Festival in 2005.

2nd Logo (2005-2008)
Nicknames: "Powered by the Nicktoons Studio", "The Engine"

Logo: A car engine with the Nicktoons Network logo on the gates to the Nicktoons Studios is shown zooming in and out as flames and smoke emit from the exhaust pipes over a cardboard coloured background with a moon and a cloud near the top right. A piece of paper with the Nicktoons Network logo slides in from the right as a crumpled ball of paper is thrown on top of it and unwraps, revealing the words "POWERED BY THE NICKTOONS STUDIO".

FX/SFX: Everything in 2D animation.

Music/Sounds: The sound of a roaring engine followed by 4 whooshing noises as the engine zooms in and out and sputtering sounds.

Availability: Extinct. Was seen after other shows that reran on Nicktoons Network from 2005 to 2008. Replaced by the fourth logo.

3rd Logo (February 25, 2006-September 2009)
Nicknames: "The Slime Globe", "Splat Globe", "The Nicktoons Globe", "The Nicktoons Splat Globe"

Logo: We see a 3-D version of the Nicktoons Network logo, an orange wireframe globe with a "splat" on the right and "NICKTOONS NETWORK" below with "NICKTOONS" in Nick's corporate font, rapidly zooming out over a brown background textured to resemble crumpled paper. The text "ORIGINAL" appears below the logo and shines, as the logo revolves to face the right.

Trivia: If you look closely at the beginning, you can see the words "ANIMATION CAPITAL OF THE WORLD", a slogan of Nicktoons Network that used between 2005 and 2009.

Variants:
 * Sometimes the text reads "ORIGINAL PRODUCTION" and/or a copyright stamp appears below.
 * Some shows use a print logo on a background depending on the show (usually black, white, or in-credit), lacking the word "ORIGINAL".

FX/SFX: The 3D network logo, produced by eXOpolis in Los Angeles, CA.

Music/Sounds: A "whoosh" sound followed by a fast-tempo, percussion-heavy jingle. The print version uses the ending theme of the show.

Music/Sounds Trivia: The music is actually a bass-boosted snippet of "Rhythm Nation" by Janet Jackson.

Availability: Extremely rare. It appeared on Nicktoons Network original shows, such as Kappa Mikey, The Secret Show, Edgar & Ellen, Nicktoons Network Animation Festival, Ricky Sprocket, Showbiz Boy, and Shorts in a Bunch. The "Original Production" variation appears on some episodes of Kappa Mikey and also on Three Delivery. It's likely available on iTunes, but on television it's extinct.

4th Logo (February 14, 2008-September 28, 2009)
Nicknames: "The Bomb", "Nicktoons Bomb", "The Almost Palindrome Logo", "BOOM!!!"

Logo: On a white background, we see a bomb explode, causing many different pieces of Nicktoons characters (Guano's blue crystal from Kappa Mikey, Zim's mouth from Invader Zim, SpongeBob's eyes from SpongeBob SquarePants, etc.) to appear. The explosion reverses and turns back into the bomb, which looks like the Nicktoons Network "globe splat" logo. The "NICKTOONS NETWORK" text from the last logo in black is under the bomb.

FX/SFX: 2D animation.

Music/Sounds: An explosion and various Nicktoons' dialogue in reverse, followed by a reverse sparking sound when the bomb reappears.

Availability: Extinct. Was seen after other shows that reran on Nicktoons Network from February 14, 2008 to September 28, 2009.

5th Logo (September 28, 2009-October 22, 2014)
Logo: On a black background, we see a gray "t" surrounded by an orange glow suddenly zooming out and flipping around horizontally, as more letters surrounded by the orange glow fly out from behind it and everything comes to a halt like it's going in slow-motion. Then the letters quickly move back and rearrange themselves to read "nickToons" (in the post-2009 Nickelodeon font) and everything shakes when they arranged.

Trivia: The logo is based off the on-air look Nicktoons had from September 28, 2009 until May 5, 2014.

Variants:
 * The color of the word "Toons" as well as the background depends on the episode or show. For example, on at least one episode of Zevo-3, the word "Toons" was green and the background was misty blue.
 * On NFL Rush Zone (which also uses the regular version of the logo), a print, in-credit version with "Toons" in blue.
 * There's a rare variant on some season 2 episodes of Speed Racer: The Next Generation where the logo (with "Toons" in blue) just appears on a black background and zooms in.
 * On Grizzy Tales, the logo is next to the Grizzly TV, Honeycomb Animation, Elephant Productions and ITV Studios Global Entertainment logos.

FX/SFX: The letters flying out and arranging themselves. For the rare Speed Racer variant, it's just the zooming in. CGI animation done by Roger in Los Angeles.

Music/Sounds: A whoosh, followed by an explosion sound, a loud electric guitar riff, a slamming sound and a cymbal crash.

Music/Sounds Variants:
 * The ending theme can be used sometimes.
 * On Voltron Force, a eerie sound, followed by a drum beat with a loud, final electric guitar riff.

Availability: Extremely rare. Seen on shows such as Zevo-3, Voltron Force, Dragon Ball Z Kai, NFL Rush Zone, and season 2 of Speed Racer: The Next Generation. Most of these shows have not aired since the mid-2010s, and very few of them have been digitally released since then. Don't expect this to appear on current prints of DBZK.
