Praise & Reviews

Gr 3–5—A pair of odd-couple detectives are out to crack the case in this second book in the series. The mayor of Kalamazoo City has just opened what he hopes to be his crowning achievement—the Kalamazoo Dome—a state of the art indoor/outdoor amusement park. But opening night is a complete disaster. Who's to blame? Is it the mayor? Suspicious business mogul Frank Pandini, Jr.? Or someone with an even higher profile? Detectives Corey O'Malley and Rick Zengo are determined to track down the culprit. The pacing is steady, with periods of dialogue broken up with bursts of action. Characters are mostly types, in keeping with the style of the genre. There are some fairly sophisticated concepts of back-room political maneuvering and the effects of an amusement park on local business sprinkled into the story that may go over some readers' heads. Black-and-white spot illustrations appear on nearly every other page, often highlighting action or dramatic moments. Give this to readers who like their detective stories with a light touch.

Travis Jonker, Wayland Union Schools, MI (School Library Journal)

The duck-billed police detectives introduced in The Frog Who Croaked (2013) find another case that exposes the seamy underside of their supposedly respectable hometown, Kalamazoo City. Someone is sabotaging the newly opened Kalamazoo Dome, an enormous indoor-outdoor amusement park that is the pet project of Mayor Davis. When rookie platypus cop Rick Zengo and his gruff veteran partner, Corey O’Malley, investigate, suspicion falls on the Dome’s three contractors—all of whom come from rival city Walhalla and have hidden connections with Mayor Davis. Though the real culprit is ultimately unmasked and, after a dramatic chase up a roller coaster, nabbed, those connections force Davis to resign, giving oily local tycoon Frank Pandini Jr. a chance to throw his hat into the ring. Stay tuned for future malfeasance. As before, Krosoczka incorporates sheaves of stock cop-show characters and tropes into his caper and illustrates it with cartoon scenes (not seen in finished form) on nearly every spread. Fans will welcome this new episode.
