In Thidwick the Big-Hearted Moose, acclaimed and prolific author Dr. Seuss tells the story of eponymous Thidwick the Moose, a kind creature who allows an incredibly interesting and diverse group of creatures take refuges in his antlers. But when the creatures (and later, hunters) go too far, Thidwick must act swiftly and convincingly.
When it was released, Thidwick the Big-Hearted Moose received mostly positive reviews. Kirkus Reviews, for example, loved the book, writing that "This - in illustrations in 3 colors and amusing rhymes tells the story of the moose whose antlers provided homes for his feathered friends." They also remarked that they thought Thidwick was the "funniest book of the year." Common Sense Media liked the book too, remarking that it is "dark" but "funny."
