Mischief is the sister of Jester who wears as Harley Quinn, except she’s in black and white.


Before she was a puppet, she was known as Moe Cartwright Russell, one of the world’s famous clown of the circus called Dunn and Duffy's Combined Circus and the only female clown of the circus. She goes by the clown name, called Ms. Silly.

On May 25th, 1990 at 9:00 PM, Moe Russell and the others got attacked by the Nazi gangsters and the employees of the circus were killed by them. Suddenly, the scientist named Robert Toulon, attacks and wipeout the Nazi Gangsters with samurai/ninja attacks, which killed them all. Robert Toulon takes over Dunn and Duffy’s Combined Circus, transformed the deceased circus employees, items, equipment and animals into marionette puppets and toys. Then, he transformed the old Circus Tent to a small new tent and turned the circus train into a small circus scale model. After that, he kept all them to his car and took them home for safe–keeping. However, Robert Toulon helped out the legacy of Dunn and Duffy’s Combined Circus to live on. On December 30, 1999 at 8:05 AM, Robert Toulon gave the soul of Moe Russell to a clown puppet and he named it Mischief.
