It's time for the twins to go on a nature expedition with Bompa. What marvelous place will they explore this time? Tidepools at the sea? The pond full of frogs' eggs? Maybe deep in the forest? But to their disappointment, they are just exploring outside the door. Yet, as they begin to search for insects, they find world-champion flyers, eaters, and weightlifters. And more tiny surprises at every turn! With their Bompa at their side, they find a way to recognize the important role of all insects.
