A teacher named Snape cycled around the schools dying his hair red before the clock struck 12. There were snakes because the Chamber of Secrets opened. Harry,Ron, and Hermione also had red hair randomly. It was very weird because by close to the end of the year almost everyone had red hair. No one really cared about the Chamber of Secrets anymore they cared about the red hair disease. But no one knew it was Voldemort actually caused this disease. Some person thought the Weasleys brought is but someone drank water and is all stopped. Everyone was safe forever.
