An idea for a world area that has sandy beaches, small scattered islands with ruins/structures including a new underwater type enemy (this could be a large piranha fish) and a new type of tree, a Coconut Tree. Sandstone can be mined here.
Along the beach various items can be collected. Crates (that get washed up, similar to other crates) can be broken down and will respawn after some time.
A Boat that is docked near the beach that can be climbed up onto so players can loot Chests and other crates (empty area similar to the camps).
Players can also find spots to dig up items and crates.
•Empty Glass bottle.
•Fishing Hook (to craft a Fishing Rod for fishing update).
**Summary of Crafting and other features
Players can find and use a new type of Saw Blade that can be attached to long handles.
Coconuts must be cut down from the tree with a Spear or other weapon that is long enough to reach.
Players can cut Coconuts into pieces, the player can cut an individual piece into Coconut Fiber, a rare item for crafting.
Players can eat the Coconut pieces.
Players can find the following assembly deck crafting recipes:
•Coconut Gourd (requires 1 whole Coconut, 4 Coconut pieces and 8 Coconut Fibers, players will need to hammer nails to finish recipe). Can hold three servings of liquid.
•Fishing Rod (if Fishing update is available, 8 Sticks, Fishing Hook and Dried Grass).
•Coconut Basket (requires 8 Sticks, 8 Coconut Fibers and 1 Leather Strap). This item is a hand basket that has 4 slots and reduces weight by -75%.
(Shoutout to u/badbananas1 on reddit for ideas, Saw Blade to cut down Coconuts, a Basket item)
**Unique Gameplay Aspect
A Shipwrecked Boat that can be explored, a type of challenge or puzzle can be completed to unlock a breathing/swimming feature.
