Who lives in a pineapple under the sea, and has done so for a decade? One Mr. SquarePants, that’s who, and he is celebrating his tenth anniversary with this 14-disc mega set that includes every episode through Season Five. In addition to collecting the episodes with guest stars like Johnny Depp and Gene Simmons, the set includes the documentary Square Roots: The Story of SpongeBob SquarePants. Spongey is a pop-culture icon for all ages, and this set proves it. If the $117 price tag at www.barnesandnoble.com is too much, there is also the $11 SpongeBob’s Greatest Hits CD featuring 16 of the squishy one’s best songs.
