Make treasure map using tea stained paper, torn around edges, and Beavers draw beach, skulls, X for treasure, trees, mountains, waterfalls etc.
Paper, tea, crayons
Stain the paper with tea and allow to dry. Scrumple up paper to make it creased. Tear the edges to give a rough appearance. Draw your map with a trail and X "marks the spot" and other things such as trees, shark pits etc. Beavers then explain to others what they have on their map.
