I hope that didn't hurt the elephant. At least it didn't seem so

Set your first brush on fire to continue your mission: To find your friends and leave this damn island

A bottle fashioned from a dried gourd with a wooden plug at the top and a cord made from woven vines to make it portable. Its length measures about as long as a forearm and with all the small nicks and discolorations it seems well worn and used.

A handmade clay bowl with rather low walls. It is coated in a sheen of black color that seems to crumble away in some places. While neither the most beautiful nor most well made thing it seems to do its job.

A cup carved from wood and seemingly sanded down with presumably sand. The upper edge is a tad too slim and almost sharp to be comfortable while also having a number of notches from long time use. The wood itself seems rotten from being left outside for too long while not being coated with any kind of water repellant.

A dirty, old piece of wood fashioned to be used as a spoon. Its surface is weathered and worn down by dirt, wind and water as well as being used over and over again, giving the surface a curious texture that is composed of smooth yet rough material.

What was once a beautiful piece of pottery now lies in shards, caked in mud and dust. Judging from its size and the way it was formed it seems that this vase was once used as a way to either store food or liquids. When taking a closer look, one is able to discern painted scenes of human figures dancing around a great bonfire in celebration.

A clearly handmade bottle from a bygone age. Its bulbous form is covered in scratches, dents and looks overall quite well worn from use. The strap on the side is caked in dirt and looks ready to crumble at the lightest of touches.
