Animated clown

From Tardis Wiki, the free Doctor Who reference

The animated clown statues were statues of clowns in Spellman's Magical Museum of the Circus in October 2009. The Pied Piper used his telekinetic energy to animate the clowns and use them as his pawns. Many of them attacked Sarah Jane and Luke Smith, Clyde Langer and Rani Chandra through the museum towards the exit. Sarah Jane disabled them with her sonic lipstick as it was able to seize up the joints of the statues and stop them from chasing them. (TV: The Day of the Clown)
