From the 4 Fat Chicks WT:
:Push the middle button on the bottom left to start the machine, then turn the crank at the bottom right a couple of times until it starts talking to you. You can talk back by pushing the buttons in the row under the row of lights. Make it talk to you until it won't talk anymore.:
Everyone had problems with this part also. It's buggy. The good news is that you don't have to do it to progress, it does give you a hint about what to do next though. Let me know if you can't get it to work and want a synopsis of what he said.
"The greatness of a nation and its moral progress can be judged by the way its animals are treated." Mahatma Gandhi
