Nickelodeon culminates the 10th anniversary celebration of pop-icon and top-rated kids' series SpongeBob SquarePants with the premiere of "Truth or Square" a star-studded one-hour prime time television event airing on Friday, Nov. 6 at 8 p.m. (ET/PT). Celebrity guest stars Rosario Dawson, Craig Ferguson, Will Ferrell, Tina Fey, LeBron James, P!nk, Triumph the Insult Comic Dog and Robin Williams appear as themselves in live-action sequences throughout the special, which follows SpongeBob and the Bikini Bottom gang as they reminisce through a series of original, never-before-seen flashbacks. Ricky Gervais narrates the special and Cee-Lo Green (Gnarles Barkley) performs a cover of the SpongeBob theme song to an all-new stop-motion opening title sequence.

"Over the past decade, SpongeBob has become one of the most beloved characters in television history," said Brown Johnson, President, Animation, Nickelodeon and MTVN Kids and Family Group. "And we're excited to cap off the year's celebration with this star-studded special anniversary event."

"Truth or Square" finds SpongeBob, Patrick, Squidward and Mr. Krabs accidentally locked inside the Krusty Krab's giant freezer on the day of the restaurant's big "eleventy seventh" anniversary celebration. As they crawl through the complex ventilation system trying to escape, the friends look back on shared memories through never-before-seen flashback moments. Highlights include SpongeBob's first visit to the Krusty Krab as a baby, a vintage Krusty Krab TV commercial, how SpongeBob found his beloved pineapple house and the time that SpongeBob and Sandy got married!

The special is hosted by Patchy the Pirate, President of the SpongeBob Fan Club (Encino Chapter), who sets off for Burbank, Calif. hoping to finally meet his long-time idol, SpongeBob, and ask him to be the guest of honor on his television special. While trying to track down SpongeBob, Patchy also pursues SpongeBob's celebrity fans and tries to persuade them to also appear on the big show.

To celebrate this on-air event, a dedicated SpongeBob category will be available on Nickelodeon VOD during the months of October and November that will include a two-minute sneak-peek of "Truth or Square" in October. The event will be fully simulcasted on Nickelodeon Mobile.
