Nukaloompas

Click the nukaloompa at the bottom platform, then click a pendulum hook to pin its axis to it. Move your mouse around until you set the desired string length and angle, then click again to place the nukaloompa there. Then, click the bomb dispenser to release a bomb so the just-placed swinging nukaloompa can grab it in the air. When the time is right, click the pendulum hook to toss the bomb to a catcher nukaloompa (to deliver the bomb) or to another swinging nuka (to pass the bomb along).
