It's a SpongeBob Christmas!

"It's a SpongeBob Christmas!" is the 23rd episode of the eighth season, and the 175th episode overall, of the American animated television series SpongeBob SquarePants. It originally aired on CBS in the United States on November 23, 2012, and on Nickelodeon on December 6. In the special, Plankton tries to convince SpongeBob to transform everybody in Bikini Bottom into jerks by feeding them his special jerktonium-laced fruitcakes in order to get his Christmas wish—the Krabby Patty secret formula.

The episode was produced in stop motion animation at Screen Novelties, and was directed by Mark Caballero and Seamus Walsh, two of the founders of the company. The animation style was inspired by those of the classic Rankin/Bass television specials. Written by Luke Brookshier, Marc Ceccarelli, Derek Iversen, and Mr. Lawrence, "It's a SpongeBob Christmas!" was based on Tom Kenny and Andy Paley's 2009 song "Don't Be a Jerk (It's Christmas)", which was also featured in the episode. John Goodman guest starred as the voice of Santa Claus. On November 6, 2012, the soundtrack album and the DVD for the episode were released simultaneously.

Upon premiere, "It's a SpongeBob Christmas!" attracted nearly five million viewers and met positive critical reception. It received four nominations at the 40th Annie Awards including Best Animated Television Production for Children (with Dan Driscoll winning the Character Animation in an Animated Television or other Broadcast Venue Production category). It was also nominated for Best Sound Editing in Television at the 60th Golden Reel Awards.

Plot summary
In the opening wraparound of the special, Patchy the Pirate and Potty the Parrot are driving in a mail truck which the former had stolen. While arguing about the directions to the North Pole, Potty sees a fork in the road and crashes. During Christmas season in Bikini Bottom, Plankton becomes angry that his evil acts have landed him on Santa Claus' naughty list, and he won't receive his Christmas wish—the Krabby Patty secret formula. However, he discovers jerktonium, an element that can turn anyone nice into a jerk, and plots a scheme. He bakes the jerktonium into fruitcakes he intends to spread around the town. To test it, Plankton lets SpongeBob taste a fruitcake, but learns he is immune to jerktonium. Upset that his plan seemingly failed, Plankton gives his fruitcake dispenser to SpongeBob, who promptly distributes the fruitcakes to all of Bikini Bottom and turns all the residents into jerks. Plankton then sends out an evil wind-up robot SpongeBob to commit troublesome deeds and frame the real SpongeBob.

The next day, SpongeBob begins to notice that everyone is acting like jerks. SpongeBob and Sandy Cheeks discover the antidote for jerktonium, and it happens to be a song. SpongeBob sings the song and brings back the residents' Christmas spirit. When Santa Claus arrives, however, he states that everyone in town is on his naughty list except for Plankton, whom he gives the secret formula. The SpongeBob robot arrives to eliminate Santa, but SpongeBob destroys the robot with the fruitcake dispenser. Santa thanks SpongeBob and gives Plankton coal upon learning that he was behind the chaos.

As Patchy is about to give up searching for Santa, he suddenly finds what he believes to be Santa's workshop. He then sees Santa with gifts in a cave and tells him his Christmas wish is to meet SpongeBob. Patchy realizes that he was hallucinating and in reality encountered a polar bear, which starts chasing him. After Santa puts Patchy on the naughty list for stealing the mail truck, he and Potty wish the audience a Merry Christmas.

Development, writing, and voice casting
Luke Brookshier, Marc Ceccarelli, Derek Iversen, and Mr. Lawrence served as the episode's writers, with Brookshier and Ceccarelli serving as storyboard directors. "It's a SpongeBob Christmas!" was based on the 2009 Christmas song "Don't Be a Jerk (It's Christmas)" written by SpongeBob's voice actor Tom Kenny and his writing partner Andy Paley. They wrote it as "...just sort of a little sample calling card of what we were thinking about." The story of the song was conceived with the help of one of the episode's writers Mr. Lawrence. Kenny explained, "...Eventually somebody at Nickelodeon found it [the song] on their desk and decided to make it into a holiday special." The network let Kenny and Paley write three more songs for the upcoming special episode (Nickelodeon eventually decided to release a soundtrack album, which became It's a SpongeBob Christmas! Album, containing the songs to coincide with the episode).

"It's a SpongeBob Christmas!" was the first full-length episode of the series to be produced in stop motion animation. Mark Caballero, Seamus Walsh, and Christopher Finnegan animated it at Screen Novelties, while Caballero and Walsh served as the directors. Screen Novelties was chosen by the show's executives to execute the animation because they had already worked with them before in other several smaller projects. These include the revamping of the opening title sequence of the show for 2009's SpongeBob's Truth or Square and the stop motion sequence of The Spongebob Squarepants Movie. Walsh explained, "They dug one of our shorts that we'd done a while back, which was called Graveyard Jamboree with Mysterious Mose, and wanted to have us apply our sensibilities to SpongeBob ... We come from the same planet as far as our sense of humor and comic sensibilities are concerned. But we also wanted to make sure that it felt like a SpongeBob episode."

All the main SpongeBob SquarePants cast members lent their voices to the episode. Series executive producer Paul Tibbitt also had a minor speaking role as the voice of Potty the Parrot. In addition to the regular cast, American actor John Goodman guest starred in the episode as the voice of Santa Claus.

Animation and filming
The animators cited the classic television specials Rudolph the Red-Nosed Reindeer and Santa Claus Is Comin' to Town by Rankin/Bass Productions as inspirations for the episode's animation styles. Caballero said, "Well, we are heavily immersed in that particular Arthur Rankin and Jules Bass style. They are big heroes of ours ... So we tapped into that knowledge for sure. We definitely use modern tricks, though. We shot everything with digital cameras directly to the hard drives of our iMacs."

Production on the episode officially began in October 2011 at Los Angeles, California, after several months of research and development. The animators worked closely with executive producer Paul Tibbitt, creator Stephen Hillenburg, and creative director Vincent Waller to ensure the cartoon characters were properly translated into three-dimensional puppets. Hillenburg and Tibbitt provided hands-on feedback on the production on a weekly basis. "They'd check out the weeklies and go back and forth with us on the various gags [...] It was really a pleasurable experience when they came to visit, because we come from the same planet. It all felt very easy and natural," Walsh said.

About 30 people—whom Walsh described "...seemed to be thrilled to work on the show"—worked on the making of the episode over at Screen Novelties. Walsh described the initial stage of production as "a very busy period for all of us ... We came in at about 8:30 in the morning and didn't leave until midnight some days. But it all zipped by pretty quickly." He said that they "felt pretty lucky because usually executives involved with productions look at the stop-motion process as annoying, but on this special, they were very jazzed and gung-go about it." To keep the production crew in the Christmas spirit, six months worth of Christmas music was played, which included 83 versions of The Nutcracker suite. According to Finnegan, it took about five months to shoot.

Set construction
Caballero and Walsh had conflicts on making sure the stop motion version of Bikini Bottom will resemble the 2D world of the series. Caballero said that "We didn't want to make exact sculptural copies of the cartoon drawings and layouts, just because it might've ended up feeling too 'perfect' or something. So we chose to re-appropriate real world objects as much as possible." Art director Kelly Mazurowski focused on "digging through salvage yards", picking the right materials to be used in the set. Caballero described this process as "'puppetizing' the world of Bikini Bottom."

Six sets were constructed on which 60 pounds of baking soda were used as snow (the crew tried to use real snow but it melted), 42 pounds of glitter were used to cover the background, and 20 boxes of breakfast cereal were used to cover the coral rocks. Over 38 different types of foam were used to make the set pieces and the characters' bodies and heads. To render SpongeBob's pineapple house, palm fronds from a tree in a school yard were used. Other props and materials used were an actual starfish, three Christmas trees (for the Patchy the Pirate's Winter Wonderland scenes), six boxes of puff cereal (to create the fruitcake inside SpongeBob's mouth), 21 pounds of googly eyes (for rivets, texture pieces, knobs, etc.), 22 pounds of woodchips (to create Sandy's treedome floor), and 24 bunches of craft flowers (to create the parade float).

Character design
According to Caballero, SpongeBob was the most challenging character to translate to stop motion. It was so "...just because of the sheer number of parts that needed to be made. We wanted to retain as much of that squashy-stretchy goofiness as possible, so he had dozens of replacement parts, like arms, noses, even various sizes of cheeks and freckles. Of course, as the main character, you really want to make sure he will charm the audience, which brings a special kind of pressure." Walsh said, "The most important thing is to capture the spirit of the character, not necessarily a literal copy of the 2D. Puppets have their own kind of energy and you have to be careful about what to include and what to leave out." On the other hand, Patchy the Pirate became the easiest character to make "because he has the most humanoid proportions."

Broadcast
A sneak-peek trailer for the episode was released in June 2012. On September 9, 2012, "It's a SpongeBob Christmas!" premiered in Israel. On November 23, 2012, "It's a SpongeBob Christmas!" aired on CBS in the United States and on YTV in Canada. It also premiered in the United Kingdom and Ireland on December 2, 2012. On December 6, 2012, "It's a SpongeBob Christmas!" aired on Nickelodeon in the United States, twelve years after the original airing of the first SpongeBob SquarePants Christmas special "Christmas Who?". According to Caballero, the decision to make the episode a CBS prime time special "came along later" and the crew "were stoked when [they] heard the news." He said it may be because "most of the classic Christmas specials like Rudolph [the Red-Nosed Reindeer], Frosty [the Snowman], air on that channel. To be included in that line up was far out!"

Critical reception
The special episode received positive reviews from media critics. In his review for the Los Angeles Times, Robert Lloyd wrote, "I felt I'd been somewhere, watching this. When it ended, I was not ready to leave." David Hinckley of the New York Daily News wrote, "It's enough to make you want to dream of a yellow Christmas." Zack Handlen of The A.V. Club called the episode "cute, and goofy and doesn't have a mean bone in its body." Mark Frauenfelder of Boing Boing said that "...they [the animators] perfectly captured the look and feel of those delightful old stop motion specials." Judge Dawn Hunt of DVD Verdict called the episode "a sweet holiday treat, punctuated by musical numbers that'll leave you smiling." He added "If you're looking for a new holiday viewing, 'It's a SpongeBob Christmas!' is definitely worthy of consideration." Paul Mavis of DVD Talk applauded the episode and felt it would become a classic that would be watched every season. Director Walsh said that "Hopefully this will become a new tradition."

In her review for the About.com, Nancy Basile's review was mixed to positive and gave the episode a score of four out of five. She wrote, "...though I disagree with a few of the animator's choices, this Christmas special is a treat." Basile criticized its characters especially the use of foam to create the characters and the way Santa Claus was depicted saying "...he looks like a pig with liver spots." The animators responded to this comment about their interpretation of Santa Claus, saying "We definitely wanted to keep an element of strangeness, almost scary aspects in the story." Caballero explained that the idea of making Santa Claus look tired and strange came when they saw a drawing of him by Marc Ceccarelli or Luke Brookshier. Caballero said, "We thought that was a great idea. So we came up with our own little back story where Bikini Bottom is the last stop for Santa. He's tired, he wants to get home, take his shoes off ... We honed in on the old descriptions of Santa being a jolly old elf. We pictured him as humanoid, but not necessarily directly human."
