In this brand-new, action-packed chapter book series, SpongeBob and Patrick have their own exciting adventures with their favourite, albeit elderly, superheroes ~ Mermaidman and Barnacleboy! These adventures usually end up doing more harm to Bikini Bottom (and the rest of civilization) than good, but it always turns out all right in the end! When SpongeBob finds Mermaidman's special superhero utility belt, he just can't stop himself from using it! But without a clue as to what each button does, SpongeBob manages to shrink Patrick! Afraid that telling Mermaidman will get him in trouble, he vows to find the right button himself. Will he figure out how to zap Patrick back to size, or will he shrink the whole town trying? Find out in this hilarious story!
