Genius problem solver Dewey takes up the challenge after a client shows up desperate to pacify his teacher. 

In this follow-up to Dewey Fairchild, Parent Problem Solver, It turns out that tons of kids have troublesome teachers, so he’s soon up to his neck in cases—from classic cases of teachers who are soo boring to bizarre cases like the teacher who leaves students scared of water—even water fountains. Meanwhile, Dewey's school starts limiting toilet paper use—to just one tiny square at a time!—and replaces Dewey’s beloved vending machines with  . . . a garden. That's no substitute for the delightful snacks Dewey lives for, so he and his best friends protest with a secret demonstration involving edible additions to school property.

But detention may be the least of their problems when some argue their actions were vandalism. Will their demands for student involvement sway the administration, or will they be caught and punished with detention . . . or worse?
