Deep down in the sea, Oliver ,a little octopus(章鱼) sat on the floor covered with sand, bored and upset. He watched pretty fish swimming in and out of rocks, which were laughing and dancing in the sea. “Why am I so different?” he said to himself sadly.
      “You are an octopus, Oliver. That’s special.” The sweet voice of Cherub,  beautiful purple angelfish(神仙鱼), always made Oliver feel better. Oliver looked up at the purple angelfish and smiled. Cherub suggested, “Let’s play hide-and-seek(捉迷藏).” They were having so much fun that they didn’t realize they had swum far from home. Suddenly, Cherub saw a large shark(鲨鱼)swimming above them. “It was Big White… the biggest , scariest shark in the sea,” she shouted to Oliver. Cherub looked at Big White hopelessly. And idea came to Oliver. He quickly sprayed(喷射)a very dark cloud of black water to the shark’s eyes. Then Oliver and Cherub escaped and got home safely.
      “Are you OK?” ask Oliver. Cherub laughed happily, “That was the most interesting trip ever! you save me just now, Oliver. I am lucky to have you as my friend!” Oliver’s face turned red. “I guess being different can be pretty cool in some situations,” Oliver said. “That is what I tried to tell you,” Cherub smiled.
