Sunny, Rainy, and their mother (Mother Nature) are fictional characters with meaningful real-life experiences. The story gives a playful look at what the sun and the rain provide for us every day. It also touches on the fact that the sun and rain can be used metaphorically to describe our moods and our feelings. Sunny is a happy, bubbly child who is powerful, purposeful, and bright. Rainy has a more serious yet sweet personality, but she is still powerful and purposeful in her own way. Mother Nature is the wise visionary who births them, loves them, and teaches them that they are different but equally important.
