The squeaker

One of Brie's new toys is a soft rubber blue bone that emits a loud squeak whenever she bites it. The causes great joy in Brie, but greater annoyance in everybody else. She especially likes it when she is able to continuously create a series of loud noises by constantly and rhythmically chewing this toy. She must think that her music is greatly appreciated, as she is always willing to start the next movement of her concerto whenever there is a good audience nearby.
