How to get extra stuff!!
1) go to the bit before the part where you can go into the water and dive for stuff... the sandy part.
2) press on any rocks there
3) you can make an 'sos' signal out of rocks, but u must collect enough first.
4) once you have made the 'sos' sign out of rocks on the sand, check back every day, and
a few days later, there will be a parachute box that has appeared. It has supplies u
need in it. This is there every few days for the rest of your time on the island
