When the earth was still young, butterflies lived only in one small corner of a forest and all the butterflies’ wings were transparent. One day a snail spots a tiny egg. A caterpillar pops out of the egg and the two becomes best friends. They happily crawl together on the plants of the forest but long to see the wider wold. When the caterpillar turns into a butterfly, the snail urges her to go see the world. The butterfly flies away. As she meets different creatures, she goes through a transformation. Her wings gain beautiful colors by the time she returns to the snail. Something surprising happens to the snail when she listens eagerly to her friend’s adventure.
