Xi Sheep and Fei Sheep are good friends. They often help Man Sheep together. But they are different from each other. Xi Sheep rans faster than any other sheep, and he is optimistic, outgoing with a smile on its face. Fei Sheep is stronger than any other sheep, but is the most careless. He does sports every day to build up his body. It's easy for him to get angry and he always disagree with other. 用HE是因为拟人手法,注意sheep单复数同型哦.
