In the set, a brown catapult was included. The brown color was to make look like wood, and it had a little plant on the side. The front plank on the catapult could be pushed as a lever to launch the rocks in the basket on the back. On either sides of the catapult, are tension wheels that can be turned around. Four spokes stick out of it, but in actuality, the wheels don't do anthing for the set, they are just for the look of the catapult.
