1. After you reached the girl, make her give you some oil for the elevator and do the puzzle to make the elevator go up. Then you'll reach the next place of the game
2. After you did all I told you on "1" , you'll reach a fan, make it angry so you can acces a room with flowers. Be sure you got the flower that was thrown by the robot woman when the robot band started to sing. Plant the flower in a pot, use the growing machine that is in the room, to grow it, and then shake the flower to get some sun flower seeds.
Solve the puzzle wich is near the exit door, open the door and go to the next room. There, in the bottom-right corner, you'll see a machine. Pour the seeds into the machine and make them sun flower oil. Reutrn to the old robot and give him the oil.
Done!
Good luck!
