Jack, Jill, and Rex are playing an exciting game of “Go and Get,” racing to find things that start with each letter the narrator calls out. “Go and Get something that begins with the letter F!” The three return in a flash (or rather in a “Zip! Zap! Zoom!”). Jack (light-skinned) brings a FROG! Jill (brown-skinned) brings a FISH! And canine Rex (brown and white, floppy-eared, pointy tail) brings “a DUCK? … Oh! This duck is your FRIEND.” Rex shows similar creativity with the letter S (he brings two ducks, but they’re SISTERS), and M (he has a dozen ducks, but they’re all MUSICIANS). So when D is called out, it’s obvious what Rex will bring … or is it? The joke never gets old in this breezy, frenetic, laugh-out-loud picture book with delightful gouache illustrations.
