Cielo, also known as Sky, was one of the first five of the herd. He was named "Mitty" by the men because he had one blue eye and one brown eye. He is a good friend of Verdad, and Estrella.
Sky is a young black colt with a white star and snip on his face. Based on his former name Mitty which meant half and half for short, he has one brown eye, and the other eye is blue.
Sky is very kind hearted and high spirited. He never gave up, even when the crocodile's tail nearly blinded him. He has a strong mouth, or he is good at saying what he believes. Sky is very cheerful, adventurous, and sweet.
