Thomas scores again after What Will Fat Cat Sit On? (2007) with another droll crowd-pleaser for the OshKosh B’Gosh set. Scornfully rejecting Duck’s hilariously persistent efforts to add a turnip, Pig and Mouse create a luscious cake—only to find themselves saddled with eating it themselves (not that they mind) when Cow obliviously falls on Duck’s turnip, rapturously declaring this birthday the best one ever. Punctuated by punch-line words (usually “TURNIP”) in red, the huge, pithy text is paired to simply drawn figures that spill past the edges, and often seem ready to pop right up from the page. From the calendar countdown on the front endpapers (Cow’s birthday is October 17th, if you’re curious) to a closing joke on the rear ones about using turnips as toothbrushes, this riotous read-aloud is guaranteed to have them rolling in the aisles.
