 * Santa's Key "The key to Santa’s house."


 * Chaco's Lipstick "Red lipstick. It has no use."

This is the first extra item that you can get in the game. To get it, examine Chaco's fireplace the FIRST time you go into her house (Otherwise it will not work), then immediately go to sleep on her bed. When you wake up you will have it.


 * Jellyfish Juice "A fluid that can quench fireplaces."

The jellyfish juice is one of the few event items that can be refilled as many times as you want. You can get it by defeating the large jellyfish in the area where you found Santa's key. It is used to put out fires.

 * Gum Base "A clump of gum."

Another item required to make the bomb, this item can be gained by using jellyfish juice on Santa's fireplace. You don't have to talk to the robot before getting this item however, so you might want to get it before you go over the cliff.
 * Charcoal "Taken from a fireplace."

Once you get all the items, talk to the robot again and he will make you the explosive. You then use the explosive to blow up the door and free the man trapped inside the house.
