. Acorn and shark were twins, but they were REALLY different. Acorn was joyful clever and the best at swimming. Shark, he was a loud introvert. He is nice to only his bosses… But shark was nice to his friends..and when acorn and shark are in big danger..shark protects his family…acorn does not mind shark too much, she knows that he is all soft and mushy on the inside! Even though the twins are sooo different. They both have one thing in common..: they are both thief’s…he also is in love with Lilac,(leader of the wolf pack)
