The first step here is to get either some shockwave grenades or a shockwave bow. Shockwave grenades can be found as floor loot or obtained from chests, supply drops or llamas. Shockwave bows can be crafted or found in chests or supply drops.

Once you are equipped with either shockwave grenades or a shockwave bow you need to find some wildlife. There are different types of wildlife that roam the island but a guaranteed spawn is outside of Colossal Crops. There is a fenced off area that contains 3 boars. Colossal Crops has lots of chests and loot so it is likely you can find some shockwave grenades.

If you happen to be elsewhere on the island and need to find some wildlife, consult the map below.
