Stink: Solar System Superhero
by Megan McDonald · Stink #5
A short, funny chapter book where a passionate second-grader campaigns to save Pluto's planetary status—and discovers empathy along the way.
The story
When Stink Moody fails a science test because Pluto was quietly reclassified as a dwarf planet, he launches a campaign to restore its status. With his friends forming 'Captain Pluto and the Underdogs,' Stink faces off against a confident rival in a week-long battle of signs, stunts, and a formal class debate. Along the way, Stink discovers that standing up for something small can bring unexpected friendships and teach you more about people than you expected.
Age verdict
Best at 6-8. Still works for 5-year-olds as a read-aloud and for 9-10-year-olds who enjoy the Stink series, though older readers may find the conflict and resolution straightforward.
Our take
Classroom workhorse: a book whose exceptional accessibility (gateway + reluctant reader rescue) and cross-curricular science content make it more valuable as a teaching tool than as a standalone entertainment experience, though solid humor and heart keep kids engaged.
