It would be good is you would add melons. You would obtain the seed from wild melon. And then you could plant it. It will grow in 5 or 10 minutes and then you will have to cut it with knife or a flint chip. You could make salad or eat it without anything. I hope this will be in the game.
melons are not quite desert biome but its close enough. in italy they have lots of melons, cactus, sand, snakes and horses. so it kinda fits in the desert.
But it could be in the jungle too.
The jungle most likely.
