The invitation reads, “Can’t you come out tonight and dance by the light of the moon?” Buffalo Flo, in her elegant bow, rounds up the other farm gal invitees, Gertie May Goose, Cassie Sue Cat and Patty Ann Pig, for the “surprise” event. They arrive all gussied up only to find that the men folk are late for their toe-tapping date. Surprise! It’s Farmer Snow’s barnyard party thanking the animals for all they do. Ryder literally takes the chorus of “Buffalo Gals” and spins off an amusing rhyming tale. The cartoon illustrations playfully depict the gals and guys “puttin’ on the ritz” with visual puns and clever accents, e.g. the magazine on Patty Ann Pig’s couch is In Sty. Adults may notice some missteps in the rhymes and a puzzling reference in the blurb to Farmer Snow’s “annual” party that seems inconsistent with the surprise buildup, but kids will enjoy the story as another silly farm-animal book, without knowing the song or its origin. Overall, the conceit is clever even though it stumbles a bit. (Picture book. 4-6)
