When you get to a place called 'temple interior' on the third island, there is an ancient forge, you have to fix it first, and then there will be an earthquake and crystal island will appear. You then use the forge to make glass. There are two ways, with 'fine sand', or with 'message in a bottle's. If you make the fine sand glass, you need 40 fine sand units. To make the 'bottle' glass, you need 2 bottles. P.S. Using the forge is the onlyway to make glass unless you use cheats.
It lets you build windows for shacks, mansions etc.
Use a mod!
On Sims Castaway to Make another Work U can Use Hard Wood
Nope unfortunately not
You use it to resurrect dead Sims. But not the dead skeletons just your Sims.
I don't see why you would need nails...? You can use the vines as rope which will be as usefull as if you had nails.
use cheats.
Not that I know of, sorry
you find parts for a shovel and then make it and use the shovel
You have to make the tool yourself, instructions on what ingredients you will need, and where to use them can be found in the pause menu.
Yeah. Just look up Sims Castaways cheats + whatever system u use.
to use the bathroom, go up to a bush, tap it, and select, "use"
As far as I can tell it's just there for nothing
