Let's go hunting.

You decide to just spend some time hunting. First you will have to wonder around looking for animal tracks. It's better to do so in late afternoon or early evening. Animal tracks are more visible at these times of day, when the slant of the light makes it easier to see the shadows made by tracks. Tracking when the sun is high in the sky is a lot harder. The easiest way to start tracking an animal is to begin in a spot where you see undeniable tracks, like in a muddy spot. From there, you can follow the tracks to areas where they're not quite as easy to detect, like trampled grass or animal droppings.

You would then follow the track hopping to eventually find the animal, sneak close to it and rush to kill it with your spear
