What is toby sweeney todd?

As an AI language model, I cannot confirm whether "Toby Sweeney Todd" is a real person or a fictional character. However, I can provide information about the character "Tobias Ragg," who is a main character in the musical "Sweeney Todd: The Demon Barber of Fleet Street."

Tobias Ragg, also known as Toby, is portrayed in the musical as a young boy working as an assistant to Pirelli, a rival barber of Sweeney Todd. He is taken under the wing of Mrs. Lovett and becomes a helper in her meat pie shop after witnessing Todd's brutal murders. As the story unfolds, Toby becomes an integral part of the plot as he survives an attempt on his life by Todd, avenges the deaths of his friends, and ultimately brings justice to the murderous barber. Toby's character is often portrayed as vulnerable, naive, and easily manipulated, making him one of the most sympathetic characters in the story.
