[3] The floors of the Krabs' residence are equipped with drain plugs so the house can be emptied after Pearl cries or spouts water from her blowhole.
A trivia book penned by former SpongeBob writer David Fain in 2000 states that Pearl "takes after her mother," implying that she is the biological offspring of Mr. Krabs and a whale.
[12] According to creative director Vincent Waller, Stephen Hillenburg received many letters requesting a Pearl origin story,[13] but was still "very much against solving [the] mystery" of how she joined the Krabs family.
[16] Pearl's name, and the decision to portray her as motherless, were an homage to the phrase mother-of-pearl, which refers to the inner layer of some sea-dwelling mollusk shells.
[20] When he was first developing the characters, Hillenburg wanted Pearl and Mr. Krabs to travel around town in a caravan boat with a whale-sized teardrop trailer connected to it; while this element did make it into the series, it was only used sparsely in season one.
[23] Animation historian Jerry Beck has stated that Pearl's breakout role was in "Bossy Boots," which he considers the episode that best established her as one of the series' stars.
She noted how Pearl was much larger than the rest of the cast, and decided to reflect the character's size in her voice by making it deep and full in tone.
"[27] Joseph Foy, author of the novel SpongeBob SquarePants and Philosophy, felt that it was difficult not to sympathize with Pearl's situation since she believes she is "more important to her father than money," but "we, the viewing audience, know differently".
[28] DVD Talk's Paul Mavis wrote in his review of Legends of Bikini Bottom that he found Pearl "annoyingly funny".
[29] In 2013, José Antonio Gómez Marín of El Mundo said that he felt Pearl brings an easily recognizable youthful tone to the show.
[31] A study by the federal office of gender equality in Mexico, El Instituto Nacional de las Mujeres, found that Pearl's roles sometimes rely on characteristics associated with stereotypes of women, such as vanity and materialism.
[39] In January 2016, Nickelodeon's parent company Viacom filed a lawsuit against the operators of a similar for-profit "Krusty Krab" restaurant to be opened in Texas.
[40] A Texas federal judge ruled in January 2017 that the planned restaurant violated Viacom's rights to the SpongeBob property, thus halting its construction.
[41][42] In 2011, the indie rock group Yo La Tengo performed a live version of Mr. Krabs and Pearl's commercial from the episode "As Seen on TV" at the El Rey Theatre in Los Angeles, California.
Included as part of Yo La Tengo's first tour, it starred Ira Kaplan as Mr. Krabs and Laura Krafft as Pearl.
[44] An episode of the sketch comedy series Robot Chicken titled "Major League of Extraordinary Gentlemen" includes a skit that stars Mr. Krabs and Pearl.
The segment, animated in stop motion like most other sketches on the program, features Mr. Krabs using crab legs as the secret ingredient for Krabby Patties.
[47] In the 2017 Broadway musical based on SpongeBob, which premiered at the Palace Theatre in New York City, Pearl is played by Jai'len Christine Li Josey.
She sings a duet with Mr. Krabs titled "Daddy Knows Best," an original composition written by Alex Ebert that highlights the two characters' differences.
"[52] Josh Ferri of BroadwayBox.com included Pearl's "Daddy Knows Best" on a list of his 15 favorite Broadway songs of 2017, calling it "a rare star is born moment...this is for [Josey] what 'Miss Marmelstein' was for young Streisand.
"[53] Jo Rosenthal of Vice wrote that "Josey nearly stole the entire show as Pearl, her voice eliciting roars of joy from the audience as she lamented the greed of her dad, Mr.
"[58] Audience reception was similarly positive; in an analysis of reviews from children who attended the musical, Newsday reported that Pearl's character was "a part of the show that everyone seemed to enjoy" and that Josey's vocal performance "was an outstanding addition.
