SpongeBob comes to work, excited about Mr. Krabs' secret surprise. Mr. Krabs takes SpongeBob and Squidward behind the Krusty Krab to reveal a big pool with a diving board. Mr. Krabs then announces that SpongeBob is the pool manager. The next day, Mr. Krabs gathered his customers outside the restaurant for the opening of the pool. But then, the customers complain that spring just started and it's too cold. The next day, SpongeBob comes to the Krusty Krab to see a huge chimney puffing smoke out of the Krusty Krab. Thinking it is a fire, SpongeBob rushes in to save Mr. Krabs, just to find different boats pumping carbon dioxide from the boats into the atmosphere.
Mr. Krabs then explains that this smoke will warm up the temperature to bring an endless summer and bring customers to the new pool.
Wanting to have customers as soon as possible, SpongeBob teams up with Patrick and starts pumping carbon dioxide, burning boat tires, and wasting electricity. Soon enough, many customers line up at the pool to get refreshment from the Krusty Krab Pool. But then, Sandy shows up, but not in a happy mood. Sandy explains that there are gasses called greenhouse gasses that keeps our temperature just right. But when you pump carbon dioxide into the atmosphere, it creates more greenhouse gasses needed, thus making the planet hotter than it should be. It is called global warming. Angered, Sandy proposes that she will not visit the Krusty Krab until they stop polluting the environment. Feeling bad, SpongeBob talks to Gary, convincing himself that she was overreacting.
The next day at work, plants are dying everywhere and the pool is overflowing with customers trying to cool down. The day after that, the water in the pool is evaporating due to the overwhelming heat.
Deciding to apologize, SpongeBob heads to Sandy's treedome to find that she, Squidward, Patrick, and Gary left for the town of Murky Waters due to the heat. SpongeBob travels to Murky Waters and announces to Bikini Bottomites that he made a mistake and that they could all work together to restore their town. Everyone heads back and starts to use bikes, less electricity, and plant more trees to restore their town. Sandy and SpongeBob then head to the Krusty Krab Pool to celebrate restoring the now beautiful town of Bikini Bottom. Mr. Krabs walks towards SpongeBob and gives him the honor of managing the re-opening of the Krusty Krab Pool in the season of summer.
SpongeBob is holding the Earth smiling and there are hearts near him, and the cover also shows the name of the book in dark green.
This book is based on the 2005SpongeBob SquarePants educational short, "The Endless Summer." However, the plot is extended and feature more characters than the short.
Each printing of the book is made out of recycled paper and printed with 100% vegetable-based inks.
Oddly, every single fish character in the book has never been seen in any actual SpongeBob SquarePants episodes.
Mr. Krabs could increase temperatures if he built a greenhouse over Bikini Bottom, which would trap the heat and sunlight.
This book was used to promote The Big Green Help movement done by Nickelodeon for Earth Day 2008 and Earth Day 2009
