Nelly and Caesar are very young animals with innocent child-like features: Nelly is a mouse and Caesar is a frog. As best friends, they live together and discover the world around them. Their awesome discoveries range from the natural world with its dramatically changing seasons, what things are called, the time, changes of temperature, the development of their perceptual awareness, and laws of nature: what goes up...must come down! Nelly and Caesar also have a delicately balanced, inner emotional world where they experience sadness, joy, fear, jealousy, and anxiety.
