Three linked mysteries, one detective. In Case 1, The Haunted Island, a tropical sloth has been tormented for weeks by a ghost that even professional ghost scientists could not locate — Frog Detective takes the case. In Case 2, The Case of the Invisible Wizard, Warlock Woods was preparing a welcome parade when the whole celebration was maliciously destroyed and the new neighbor vanished. In the series finale, Corruption at Cowboy County, Frog Detective and Lobster Cop investigate a sheriff-less town where a deceptively simple mystery unravels into a genuine conspiracy — the most twist-packed case yet, and a love letter to fans of the series.
