Astrophysics facts combine with everyday second-grade school experiences in this lively chapter book in the Stink series. Shocked to hear the scientific fact that Pluto has been declared too small to be a planet, Stink stands up to both grown-up scientists and other kids when he starts a campaign to let Pluto back into the solar system. He even makes bumper stickers that read "Honk if you love Pluto." The funny words ("double freaky-deaky") and silly scenarios, illustrated in Reynolds' wry, informative black-and-white drawings, make for a fast read about the triumph of the little guy and the wonders of the universe.

While studying for a science test, Stink learns about Pluto's "demotion" to dwarf planet status. He grows determined to restore it to its place of glory. His second-grade class divides into pro- and anti-Pluto factions, complete with protest signs and an election. Stink's enthusiasm is contagious, and readers will enjoy using the "Mnemonic Comics" cartoons to learn planetary facts along with him.

PreS-Gr 3 In this installment, Judy Moody's brother sticks up for Pluto, as it has unfairly (in his estimation) been demoted to dwarf planet status. Stink, defender of all things small, accepts the challenge of trying to convince his classmates that Pluto should still be considered a real planet while his nemesis, Riley Rottenberger, argues the opposite. The story is predictable but sweet as the smaller things in life are championed. Stink is an entertaining character and his audience will appreciate his jokes. The series of solar-system comics are likely to pull reluctant readers into the story while offering fun trivia about the solar systemincluding Pluto. A fun addition to a popular series.
