At this stage of Goodbye Deponia, call the Organons. Go to the right. Move the lever down and click "stop". Press the pedal on the lift floor flap. Remove the throttle, press the pedal again and move the lever downwards. Click "Stop". Go further to the right - Rufus will give a speech, no matter what dialog options you choose. Then you have to sing the anthem - it's a minigame, in which you have to set the notes on the stave in such a way that the Rufus sings in good tones. The heart above the heads of the Organons stands for correct positioning, the dots for a small error, the clouds for a large one. The solution in the photo above.
