The way it launched was...
There was a box inside that had a bottom that moved up and down. The bottom piece had flanges on two opposite sides that stuck out the slots in the sides of the box. On the out side of the box, was two long springs anchored on each side of the flanges, and lapped over the flanges. That way, when you pushed on the bottom, you are pushing on the tension of the springs. The top of the box had double doors, where one laps the other. A motor with an arm would turn to put the arm on top of the doors, holding them shut.
So you compress the rocking into the box, which also pushes down on the spring loaded bottom, and the doors are closed, the arm is moved into place, and you're ready to go.
With the two springs and the spring in the puppet. It really did shoot like it shows in the picture.
Hope that all makes sense.
