In addition to the ten main characters, SpongeBob SquarePants has a large amount of background characters. They are identified by the artists and animators with individual model numbers. These model numbers correspond to when the characters were designed in production. The following is a list of background characters, sorted by their model numbers.
An enormous crowd filled with many different incidental characters.
"Squeaky Boots," the second episode made for season 1 in production order (code #102), was the first produced episode to feature incidental characters. As a result, the first row of incidentals (incidentals 1-11) were all first designed for "Squeaky Boots." Despite this, Incidental 18 appears in that episode as well.
Some characters have been removed from the model sheets, mainly between the second and fourth seasons. Like most animated series, many SpongeBob episodes are worked on at the same time, leading to several incidentals with later numbers appearing in episodes before others with earlier numbers.

Trivia
- Most background characters have two models: one for their daytime color palette and another for their nighttime color palette. For example, Fred's palettes are labeled "001-DAY" and "001-NIGHT."
- According to Jay Lender, several of the original incidental characters were removed from the model sheets during the second season after their models were lost in the shuffle during revisions.[1] As a result, many episodes featuring them in storyboards (such as "Christmas Who?" and "Mermaid Man and Barnacle Boy III") had them replaced with different character models.
- The numbers for these characters are known from storyboards. Specifically, numbers 33, 35, 61, 62, 70, and 71 are known from the storyboards of "Christmas Who?."
- Fred, Scooter, Old Man Walker, and Sandals are currently the only incidental characters with official confirmed names by the SpongeBob crew. Other characters have been given various names throughout the show, but these are limited to single instances and do not carry over to other episodes.
- The models for Incidentals 30 and 30A are redraws of the anchovies from "Help Wanted." Unlike the anchovies in "Help Wanted," these incidentals are solid blue and brown, and the brown anchovies have blue shirts instead of white ones.
- In many episodes, duplicate background character fish can be seen in crowds.

Four of these incidental model sheets were uploaded by Vincent Waller to his Twitter in February 2018; the first three sheets were uploaded on February 8, 2018 and appear in "Goons on the Moon." The character models for the Rock Bottomites were in the files of the PS1 version of SuperSponge. Adam Paloian uploaded to his Twitter Incidental F4's character model on August 1, 2017 and three Empty Head Society sheets in January 2019.
