Shelter
One of the things you'll need to survive is shelter. There aren't a lot of caves in the grasslands so it's not like you're going go find one and be set. Some of the best supplies for shelter are trees and bushes for the walls, leaves and grass for the roof, and just a little space to exit/enter.

Trapping and Killing (and also cooking)
To trap and kill the animals for food we're going to use our bear trap and our bow knife. With the bow knife we're going to sneak up on an unsuspecting animal and shoot the knife into them or run up and stab them. With the bear trap, we'll set up some food on the trap and when an animal is caught we'll go to them and kill them with the knife. To cook it we'll get wood from the nearby trees and set it into a little pit we'll dig up. We then set it on fire using the lighter and use a stick to cook the meat over the fire.
Water Finding and Purifying
To find water we'll either search a big area for ponds or things and if we don't find anything we'll go to the trees, stick a hole in them with the knife, and use the tree tap to drain the water out. Once we have water, to purify it we'll make a fire and boil the water in a wooden bowl and let the evaporation float through a leaf net we make and into another bowl on the top. Once the gas-form water is water again we'll drain it out and pour it into the canteen.
