Detective Rick Zengo is a rookie working on his first case with a new partner. What starts out as a seemingly simple missing person case turns into a mystery involving organized crime and some high-ranking government officials. Writer Jarrett J. Krosoczka has put together an interesting cast of characters in The Frog Who Croaked, his first offering in the Platypus Police Squad series. Krosoczka is best known for his Lunch Lady graphic novels, and this book is full of his amusing illustrations. Anthropomorphic animals abound in this intriguing story with plenty of humor to appeal to both young and mature readers.
Zengo, who still lives with his parents, is trying to prove himself both to his fellow cops and to his family. He is the grandson of one of the most revered detectives in Platypus Police Squad, so he feels a lot of pressure to do his best. He wants to be taken seriously as a good cop on his own merit, but it takes a hard lesson from his more seasoned partner Corey O’Malley before Zengo can do so. The dynamic between Zengo and O’Malley may remind some readers of many cop show partners including Starsky and Hutch or Friday and Gannon. Krosoczka lays the groundwork in The Frog Who Croaked for more good-natured bickering and interesting adventures with this pair of detecting platypuses.
