The SpongeBob Squarepants Movie trivia
The song "Goofy Goober Rock" is a spoof of the song "I Wanna Rock" by Dee Snider.
The SpongeBob SquarePants Movie website was hacked around the time the movie was released into theaters. If one explores Bikini Bottom on the main page, the ghostly letters "SB" appear in the bottom-left corner. If one clicks them, it takes them to the fansite, www.spongeblogger.com. The site's creator got into serious trouble for doing this, but was forgiven seeing as he had done no serious harm. The link, however, was never removed and still remains there.
