When Sophie accidentally sends her stuffed rabbit Felix on a balloon ride up into the sky, his adventures are just beginning! He hitches a ride on a space rocket, and from the moon he sees how beautiful our Earth is. Little does he know that soon he will be exploring all the blue, white, green, and yellow places he saw from so high up above. At each stop on his trip, he sends Sophie a letter: from the planetarium, the moon, the North Pole, a tropical island, a rain forest, and a desert.
Children with love opening the envelopes to read Felix's special letters as much as Sophie does, while they learn about the importance of protecting our beautiful world. But will this world-traveler rabbit ever make it back home?
