A sudden summer thunderstorm sends the squirrel children scampering. It’s a hot summer afternoon. Nothing is stirring. Not the frogs, not the flowers, not even the grass. Then suddenly birds are flocking overhead. Small animals are racing for shelter. The rain starts pouring down. Thunder booms. Lightning cracks and flashes. Mick, Mack, and Molly are caught in the midst of one of the most exciting moments of summer: a sudden summer thunderstorm. It can be scary, but for the three squirrel children, safe and dry in a cave, it brings new friends.
