Here your easiest source of fodd would be grasshopers, in other words insects and fish. If you have amazing speed and awesome stealth then you might beable to get a buck
But the chances of that happening arent great.
There is a tee called the Apple Leaf. It is also called the Rain tree because a bug by the name of the spittle bug sucks the nutriants out of the leaves and it slides down the bugs body and falls. and normally when you walk past you will get hit by the liquid. It also has little umbrella thingys lol i think they are seedpods if im correct and when you throw them in the air the hover down.
Now i am telling you about this tree because its bark when crushed and ground aswell as its root can be used to poison water in order to kill fish.
This is probaley the easiest wat to ge food.
The other options are berrys and fruit. Before you eat a fruit or berry etc open it up and dab a little bit on your tounge, if it is bitter DO NOT EAT IT! if it tastes fine wait for about an hour to see if you get any medical reactions. if not take another small taste and repeat the proscess.
Do not eat brightly coloured insects! this means tey are poisenous. do the same tasting method as above. but NEVER eat brightly coloured insects!
