Harvey, upset when his Darth Paper finger puppet brings humiliation, gets Dwight suspended, but Origami Yoda asks Tommy and Kellan, now in seventh grade, to make a new casefile to persuade the School Board to reinstate Dwight.

In this final book in the series, the seventh graders of McQuarrie Middle School and their Star Wars-inspired Origami finger puppets go on a field trip to Washington, D.C., on what proves to be a very long trip full of shifting alliances, betrayals, carsickness, and sugar rushes.

"Dark times have fallen on McQuarrie Middle School. Dwight is back--and not a moment too soon--as Kellen, Sara, and the gang face a new Menace: the FunTime Educational Program. FunTime is supposed to raise students' standardized test scores. Instead, it's driving everyone crazy. The students turn to Origami Yoda for help"--

Horton, an upstanding kitchen boy in a castle in nineteenth-century England, becomes embroiled in a mystery surrounding a series of thefts, which is also connected to the pursuit of a very eligible and wealthy young lady's affections.

McQuarrie Middle School's students miss Origami Yoda when Dwight leaves for Tippett Academy, but he sends Sara a paper Fortune Wookiee that seems to give advice just as good as Yoda's--even if, in the hands of girls, it seems preoccupied with romance.
