Help stopping movement of object inside another

I have created a ball bp that is used as a rolling ball. I would like to put something in the ball and not have that item move with the ball. The idea is to place a animal inside the ball and have that item animate as if it is making the ball move. I am trying to start small and use a cube and have the cube stay stationary but it continues to move with the ball. Is there a setting I can select with the cube to keep the cube in the position it is in within the blueprint while the ball moves and shows its spinning. I tried locking the position within the constraints and this did not due the trick. I also tried making the cube immovable but since it is attached to the ball it only causes the whole blueprint to be unmovable.


Figured out how to make this work for anyone else who is wondering
