1st Logo (April 1, 1999-October 1, 2002)
Nickname: "Head Bulb"
Logo: On a blue BG, we see a Naggin logo with nothing on top. What appears to be a drill pops up on top of the logo, and is forced out, revealing it to be part of a lightbulb (the logo shuts its eye and grits its teeth once this happens). It turns upside down, lights up (turning the BG yellow), and smiles. The letters in the logo rearrange themselves to be right-side up, and "ORIGINAL" appears below.
Variant: This was also used as network ID, but the word "ORIGINAL" (and the copyright notice) are removed.
FX/SFX: All of the animation.
Music/Sounds: A "screwing" sound as the lightbulb piece appears, and when the logo lights up, there is music that sounds "desert"-like, accompanied by various sound effects, which include the word "Naggin" being spoken in Dexter's voice (from Dexter's Laboratory).
Availability: Extinct; appeared on A Walk in Your Socks (1999-2002 episodes), Donkey!, and the first season of Stop Pestering Me, Sesame. Stop Pestering Me, Sesame still airs on EGG Kids Sprout, but this logo is cut off on Sprout airings.
Scare Factor: None.
2nd Logo (October 1, 2002-September 11, 2005)
Nickname: "Mentally Created Tree"
Logo: Against a blue sky over a field of dirt, the sun is rising and we see the Naggin logo. A tree quickly grows on it, with fat little birds approaching and a banner with "ORIGINAL" on it appearing.
FX/SFX: Just cute animation.
Music/Sounds: The second half of "My Bologna" by "Weird Al" Yankovic.
Availability: Last seen on Oozy and Teach Your Preschoolers How To Whine Like Adults re-runs on the now extinct Naggin. Reruns of Teach Your Preschoolers How To Whine Like Adults on Robotnik Jr. have the logo plastered by the Party X Studios "Shaking School" logo. However, Oozy still airs on Robotnik Jr. with this logo intact!
Scare Factor: None; it's harmless, unless you dislike baby shows.
3rd Logo (September 12, 2005-September 27, 2009)
Nickname: "Naggin Horn"
Logo: On a pattern background, we see the Naggin logo on the left with the curved tuba facing to the right on the head. A white ribbon reading "ORIGINAL" comes out of the tuba and birds are handling it with their rear-ends.
FX/SFX: Same as the first one, but with less of the "cute"-ness.
Music/Sounds: A guitar tune mixed with strings and fart sound effects, which was composed, written and played by Jhas Blujk and his brother Nick Blujk and sister Lisa Franks-Blujk.
Availability: Possibly extinct, this can only be seen on re-runs of Bobby's Big Music Show on Robotnik Jr.
Scare Factor: Same as the 2nd logo, plus the fart sound effects in the audio may get to some obnoxious babies.
4th Logo (2006-2009)
Logo: On a white background, we see the Naggin logo. Above it, we see some mentally-created skyscrapers.
Music/Sounds:The ending theme of the show.
Availability: Rare; seen on Bluey Dooy Doink on Robotnik Jr.
Scare Factor: None.
