Something strange is happening to the sixth grade—and it’s up to student scientist Wilmer Dooley to crack the case in this hilarious mystery “filled with entertaining twists and nutty characters” (Publishers Weekly).If there’s one important thing Wilmer Dooley’s dad always says, it’s this: “Where are my car keys?” Okay, maybe not that. He also says: “Observe!” Wilmer has always known that the greatest science comes from the keenest observations. So when he observes his classmates looking a little green…and orange...and chartreuse-fuchsia polka-dotted...he knows that it’s up to him to find the cause of this mysterious illness—and its cure. But with his arch nemesis, Claudius Dill, hot on his heels; the eagle-eyed biology teacher, Mrs. Padgett, determined to thwart his plans; and a host of fluorescent classmates bouncing off the walls at increasingly dangerous speeds, can Wilmer prove he has what it takes to save the sixth grade from a colorful demise before it’s too late?

Student scientist Wilmer Dooley and his friends—and enemies—are back with another hilarious mystery to solve in this zany, action-packed sequel to The Contagious Colors of Mumpley Middle School.Wilmer Dooley can’t wait to be a seventh grader. But first, he really can’t wait for the 45th Annual State Science Fair and Consortium. It will be a blissful summer weekend spent hanging out with Ernie and impressing Roxie with his dazzling project on bacteria. But Wilmer’s dreams come crashing down when he arrives at the dilapidated Sac à Puces Palladium, Lodge, and Resort-Like Hotel. First, his old biology teacher, Mrs. Padgett, is a chaperone—and she absolutely despises Wilmer. Next he learns that the fair’s final activity involves being stranded in the dark woods and trying not to get eaten by bears. And worst of all, his arch nemesis, Claudius, is there—and he’s brought along his equally rotten cousin Vlad. Wilmer quickly begins to suspect that the two are planning something horribly sinister. But as he grows more and more concerned, the other kids begin behaving more and more strangely...almost as if they’re being brainwashed. And when Wilmer discovers the diabolical scheme that’s afoot, it’s even more terrible than he had imagined—and he may be too late to stop it.
