Bonnie and Ben are two rambunctious siblings who love to rhyme. One day, on a walk with their friend Skinny Doug, they recite beloved nursery rhymes for each new thing they encounter. When they reach a hill, they recite "Jack and Jill." When they see a sheep, they recount the story of "Little Bo Peep." The nursery rhyme characters join them on their lively walk until, with a last "Twinkle, Twinkle Little Star," the pair arrive home and snuggle into bed.
