The Matryoshka Doll was a room furniture item in Club Penguin. The first 1000 players who bought a membership in the Russian version of the game received an e-mail containing a code to unlock the item.
One appeared at the Ski Village during the Muppets World Tour, behind Dr. Bunsen Honeydew and Beaker. If hovered over, it would open and seventeen more identical matryoshkas, each successively smaller, would fall in a clockwise spiral.
