The crash test dummy in Body Drop 3D exists to be knocked over, and you have the tools to do it. Each level places the ragdoll somewhere with obstacles around it, and you throw balls at it to cause as much damage as the physics allow. More damage means more points and new scenarios to unlock.
Hits to the head or legs are the best way to make it topple. Before throwing, look around the scene: a long fall or a hard object nearby turns a small push into a big score. Another game played entirely with the mouse is FNAF Clicker.
