Kitchen Boy
From Tardis Wiki, the free Doctor Who reference
The Kitchen Boy was one of the deadly pawns used by the Celestial Toymaker against Steven Taylor and Dodo Chaplet when they were trapped in his realm. His appearance was that of a chef. When not in a contest, the Kitchen Boy stayed in doll form.
He also appeared to Steven and Dodo as the Knave of Hearts and Cyril. (TV: The Celestial Toymaker)
