Froo was born in New York City. He grew up in a family of theater mice. For generations they had been a family of actors, singers, vaudeville performers, stage hands, directors, costumers and dancers. They lived in an old attic trunk above one of the oldest theaters in the heart of the city. Even when Froo was a young mouse, he loved performing Shakespeare the best. Froo has never had a leading role, although he was the understudy for Romeo in the play Romeo and Juliet. Froo loves how he looks and takes great pride in his hair styles. He is a mouse with a "doo." Out of all of the company puppets, he is the one most likely to be i in a fashion frenzy. He likes pretending and play-acting as different characters.
