Green Slime Ooze News Nick Mag Oct 2002

The October 2002 issue of Nickelodeon Magazine featured the "slimelights" of green slime's appearance on television over the prior 20 years.

Slime is a (usually) green semi-viscous substance that has been synonymous with Nickelodeon since its introduction on You Can't Do That On Television. It is typically dumped on a person's head in an act of either humiliation or celebration, in an act called being slimed. On You Can't Do That On Television, saying the phrase "I don't know" would result in the speaker getting slimed. Slime has been used on every messy game show on Nickelodeon in some way, shape, or form, and has become a staple of the Kids' Choice Awards. The slime is simply a mix of vanilla pudding, apple sauce, green food coloring and a little oatmeal.

Appearances in shows

You Can't Do That On Television

Screen shot 2012-09-30 at 2.59.18 PM

You Can't Do That On Television introduced slime in 1979.

If anyone on the show said "I don't know", they would be slimed. Occasionally, the slime would be a color other than green.

Double Dare

Slime was used in several Physical Challenges and obstacles, including the Slime Canal and the Nick Blimp (which essentially was just the contestant getting slimed).

Wild and Crazy Kids

Slime was only used in one game, but on a few occasions during the "host segments" someone would get slimed. Wild and Crazy Kids would more often use their own slime-like substance, a thicker substance called blap.


The slime appeared as the "Special Topping", dropped onto the participants in Playland after their game was finished and they were awarded the Silver and Golden Hot Dog trophies.

Figure It Out

Halfway through the game, a "Secret Slime Action" would be announced to everyone but the panelists. Once one of the panelists (usually Danny Tamberelli) performed this action, they would be slimed. Occasionally, the slime used on Figure It Out would be yellow. On the revival an extra sliming action, called the "Word of Honor", was introduced, where one of the words in the puzzle would cause the contestant to get slimed.


In Rugrats in Paris: The Movie, the Ooey-Gooey World ride at EuroReptarland is filled with green slime.

SpongeBob SquarePants

In the episode "Graveyard Shift", when Squidward is trying to remember the signs that signal the approach of the Hash-Slinging Slasher, he then notices the walls behind him are oozing green slime. He initially thinks this is the third sign, but then remembers, "No, wait, they always do that."

Fanboy & Chum Chum

In the episode "Slime Day", an event called Slime Day rolls into Galaxy Hills and whenever someone shouts out the secret phrase ("I don't know"), they get covered with slime. Fanboy and Chum Chum try to get slimed too, but they don't due to not knowing the secret phrase and coming up with secret phrases of their own. Meanwhile, Fanboy and Chum Chum also go to Nickelodeon Animation Studios in Burbank to talk to the Nickelodeon President about the secret phrase.

The Loud House

The episode "How Double Dare You!" centers on Lincoln and his sisters wanting to get a spot on Double Dare when they hear it's coming to Royal Woods, hoping they can get slimed themselves. Sure enough, they all eventually get slimed at the very end of the episode. The original title card for the episode also depicted Lincoln covered in green slime.

Slime Geyser

Slime Geyser

One of Nickelodeon's trademarks was the Slime Geyser, a fountain located just outside of Nickelodeon Studios, which would spew the goo upwards every fifteen minutes. In its early days, it would shoot forcefully enough to get those standing too close slimed, though the pressure was reduced in later years. The fountain was removed in May of 2005.


Several slime-related products were created and sold in the past, including Green Slime Shampoo, which was used as a parting gift on Double Dare, and Slime Shoes. A toy called Slime was also made; however, it did not prove to be as popular as the similar Gak.
