The shell is at least partially filled with a liquid. The cells have passageways formed therein, that preferably have different sizes, to provide fluid communication between the cells so that the liquid flows in a manner to simulate natural breast movements. Cells are interconnected with the shell and with each other so as to avoid excessive movement.
