The Muse was an android which had the power to make people do musical routines against their will.
The Muse was made by an elephant-like race for their Maharani as an amusement, but when the Shasarak found out her powers could be used for destructive purposes they invaded and tried to steal her. She was sent off in a spaceship. The ship was gunned down and she was the only survivor. The townspeople took her in but the Shasarak were still on her trail. The Eleventh Doctor soon arrived and managed to find a way of restoring the Muse to full power. She then used the power to stop the Shasarak. (COMIC: Planet Bollywood)
