Cleverly riffing on the popular children’s song and also giving the story wryly humorous Law & Order vibes, Teague’s text will work well as a read-aloud for group and one-on-one sharing alike. Colorful acrylic illustrations are amusingly exaggerated, especially the expressions on the human characters. Here a ha ha, there a ha ha—this one’s bound to elicit chuckles. -- Kirkus * February 15, 2026 * Moove over, Law and Order—a daffy prank spree is unfolding at the Old MacDonald farm in this barn burner of a mystery spoof. . . . Teague brings a deadpan quality to acrylic scenes that are here paired with sly song references (“Just as I suspected,” Officer Busby quips. “Everywhere a smell-smell”) and hardboiled dialogue (“Someone made your chickens look foolish. I want to know why”). And while it ultimately appears that crime does pay, even actions-have-consequences hardliners should get a giggle out of this farmyard whodunit. -- Publishers Weekly * 12/15/2025 * In Teague’s humorous whodunit, the scene of the crime is Old MacDonald’s farm. Officer Busby is taking the mystery seriously, speaking the deadpan patter of old detective movies. . . . Teague’s signature illustration style fills the pages with barnyard critters, the befuddled farmer, and the diligent officer, all in a muted acrylic palette. . . . a good pick anywhere Teague’s books are popular. -- School Library Journal * 12/12/25 *
