Instructions
Play through the mission until you crash while testing G's sled. Pick up the survival guide and the rope from the crash debris, then go straight ahead towards a bush in the distance.
Move the screen to the right and you'll see a tree with a pot hanging from its branches. Click on the tree a few times until you shake the pot loose, then pick up the pot and place it in your inventory.
Go slightly to the left of the bush, then go straight ahead when you can see a stream in the distance. Move the screen to the left to make the stream appear larger.
Click on the pot in your inventory, then drag it to the water. Click anywhere on the stream to fill the pot with water.
