There in Count Olaf's House you will find a picture of a magafine-glass burning a ant this is the passage way to the cellar.
First, 3 people start to dance. One of them will hold the marriage certificate up, and you will have to burn it. Don't aim for the certificate, aim for the person holding it up. Remember, you have limited time. You burn half of the certificate, and move on to a battle.
To get more "happiness", burn up the figures the people are holding up. Also, you need to do this to burn Count Olaf, so you have to work fast on this. You are NOT timed. As soon as you hit the Count, the Hook-Handed Man will start shooting watermelons at you. It's easy the first time. The second time you try to get Olaf, watermelons are shooting at you still. After you burn the whole certificate, you don't have to shoot anymore watermelons, and your done with the game.
Some people have told me, "I have searched Count Olafs house for a extra puzzle piec, but I can't find it!!!" Well, have you look in the cellar? As soon as you get to the bottom of the stairs in the cellar, there is a box with a puzzle piece in it.
