Premise
When SpongeBob Squarepants wins another streak for "Favorite Cartoon" on the Nickelodeon's Kids Choice Awards 2020, The "saltiness" has corrupted an individual in order to lure all cartoons to go at each other's throats and against SpongeBob for the sake of the fans' tirade on the series. And when Aaron and the Mane Six and his friends are informed of a "cartoon war" by Rick Sanchez, then they must take action to stop all the cartoons from going to war against each other, even SpongeBob. But there will be many challenges to try to get along and with a bit of condition on their friendly competition in terms of networks and brand identities, as well as trying to divide the good from the bad when it comes to fandoms.
