How to overlay two plots created by functions?

I have a function that randomly generates 9 balls within the parameters of a pool table. I have another function that generates a animated pool table. I need to have the balls randomly generate on the animated pool table. Can any help me out with this.

hold( hAxes, 'on' )

after plotting the table and before plotting the balls should work unless I'm missing something.
