Behind Closed Doors is an extremely rare book of SpongeBob SquarePants drawings by official storyboard artists depicting the characters in inappropriate adult situations, made in 2001.

History

Around 2001, several crew members made Post-It notes of SpongeBob characters depicted in vulgar and obscene situations solely for humorous purposes. One significant drawing was a storyboard panel for the "Chocolate Milk" commercial released in 2001 in campaign with Got Milk? where the milk is replaced with an inappropriate liquid. The series of drawings were adapted into a book that was also given to people who regularly hung around the original Nickelodeon Animation Studio.

Trivia

• This book was considered lost media and completely unknown to the public until July 18, 2023 when YouTuber LSuperSonicQ made a video for it, revealing he received an email from someone who had the book in their possession from their original visit to the studio in the early 2000s.
