You are in your balloon house. The idea is to get Toni with you to the balloon. The Chronocar plays an important role and you might have to revisit some of the puzzles second time.
Unlike normal walkthroughs, in Nice Game Hints you can select just the puzzle you want hints for. Here are listed the puzzles for "Kuvaq" in Deponia Doomsday. The guide you choose only contains information about that puzzle, reducing possible spoilers for other puzzles.
