Little Quack and his four siblings discover a frog, Little Ribbit, in their pond. He wants to play. While the other ducklings are wary of him at first (he’s too little, too green, and a FROG!), Little Quack has no such hesitations, and he is determined to make a new friend, no matter how different he may be. Quack, quack, ribbit, ribbit! Off they go. As it turns out, the frog’s sense of fun perfectly matches that of the ducks. He loves to splash, squish in the mud, bounce on a log, and dunk in the water. As their play moves from one activity to the next, the other ducklings join in the fun one by one.
