My Happy Book: SpongeBob's 10 Happiest Moments is a SpongeBob SquarePants book written by Alison Inches and illustrated by Stephen Reed. It was released on September 1, 2009 and was made to celebrate the series' 10th anniversary.
"SpongeBob remembers ten of his HAPPIEST moments ever in this special anniversary edition novelty! From his first Christmas to his first night shift at the Krusty Krab; from the day he met Sandy Cheeks to his star-studded mopping performance at the first (and last) Krusty Krab Talent Show! With various novelty flaps, pull-tabs, and spin wheels throughout, this walk down memory lane is sure to have readers crying tears of laughter!"
Despite being made to celebrate the show's 10th anniversary, it was released exactly four months after the 10th anniversary, on May 1, 2009.
