This is unlocked after the very first scene in the game. Put the cursor over the tub and press "X." After the tub falls over, click "X" on the pile that was under the tub. After the pile falls down, click on the robot head laying nearby. You're almost put together at this point. Hover over the robot body underl you see an arrow pointing up, then click "X." This will stretch your character up and allow you to reach a "doll" at the top of the pile. Once you have the doll, hover your cursor at the very top so you can select the doll from your inventory, then click on the "rat" that's running around on the bottom. The rat will give you the legs so you can walk. Walk to the right and grab the magnet at the very top and click on the string spool to get a piece of string. Hover at the to to bring down the inventory meny. Click on either the magnet or the string and then click on the other item that wasn't selected, which aturns the two items into one, leaving you with a magnet tied to the end of the rope. Walk over to the far right and click on the poll and have it lean over the cliff. Select the "magnet string" from invetory and then click on the pole. Your character will go down and the trophy will pop.
