Beep! Beep! It's Halloween! Driven by a dapper frog in a black cape, Little Blue Truck is picking up his animal friends for a costume party. Prereaders can lift the flaps in this sturdy board book to find out who's dressed up in each costume. Will Blue wear a costume too? You bet. Jill McElmurry is sure elicit laughs with her folksy depictions of ballerina ducks, witchy squirrels, and cows dressed as clowns and queens.
