Hayden and Henry Holbrook were twins. People often think that identical twins are the same in every way, but this couldn't be further from the truth when it came to Hayden and Henry. The boys were exact opposites. Sure, they both had the same mane of golden, floppy curls, the same piercing, blue eyes, and the same cheeky smile, but that was where the similarities ended. Hayden was the brainy one; he was a walking encyclopedia. His main areas of expertise included computer coding, dinosaurs, and British folktales (Robin Hood was his favorite), but in general, he knew a lot about a lot of things. Hayden always had his nose in a book and loved to watch documentaries on the TV. He was painfully shy and hated being outdoors in nature. Henry, on the other hand, preferred joke books to informative ones. He was always clowning around and making others laugh. Henry had a real heart of gold and was always willing to help others. He also loved sports and was a champion swimmer.
