Upon its premiere, "The Legend of Boo-Kini Bottom" was watched by 2.210 million viewers, making it the eighth highest-rated cable program of October 13, 2017.

Meanwhile, the Flying Dutchman becomes happy that the residents of Bikini Bottom are scared on Halloween, but SpongeBob's laughter interrupt him, and he descends to the town below.

[1] "The Legend of Boo-Kini Bottom" is produced by Screen Novelties in their second partnership with the series following the season 8 episode, "It's a SpongeBob Christmas!"

[1] Mark Caballero and Seamus Walsh of Screen Novelties served as directors, while Chris Finnegan produced.

The episode was written by SpongeBob staff member Mr. Lawrence, with Brian Morante serving as the storyboard director.

They felt that the medium of stop motion helped to enhance "the creepy factor" of the series' look, making it a good fit for the holiday.

[2] According to Walsh and Caballero, one of their short films prompted Waller and Marc Ceccarelli to contact them, as they felt that the studio shared a similar sense of humor to SpongeBob.

[4] In contrast to most SpongeBob episodes, which take about nine months to finish, "The Legend of Boo-Kini Bottom" took a year to complete production.

[2] Screen Novelties were sent animatics, storyboards, and voice tracks, and were tasked with figuring out how to translate the 2-D sets and characters into 3-D stop motion.

In making these sets, they incorporated 15 boxes of breakfast cereal, eight pounds of glitter, hundreds of popsicle sticks, black lights, and 315 strips of toupee tape.

[9] In his review of the DVD release, John Corrado of The Joy of Movies praised the animation and said, "For fans of SpongeBob, The Legend of Boo-Kini Bottom works as an amusing and offbeat Halloween special that has some fun reimagining the 2D characters in a different way, and for everyone else it’s an odd little curiosity that is worth checking out.
