Upon waking up in the jungle, your immediate priorities are water, food, and shelter. Here's a step-by-step guide:

- Find Water: Locate a clean water source. Rivers are common, but be wary of contaminated water (indicated by murky appearance). You can drink directly from clean sources or collect water in a Coconut Bidon or Turtle Shell.
- Gather Basic Resources: Collect Small Sticks, Long Sticks, Stones, and Leaves. These are fundamental for crafting tools and starting a fire.
- Craft a Stone Axe: Combine 1x Small Stone and 1x Small Stick in your crafting menu. This is your first essential tool for chopping down small trees and defending yourself.
- Start a Fire: A fire provides warmth, cooks food, and purifies water. Gather Tinder (Dry Leaves, Bird Nests) and a Hand Drill (Small Stick + Small Stick). Combine them to start a fire.
- Find Food: Look for fruits (Bananas, Brazil Nuts), mushrooms (be careful, some are poisonous!), and hunt small animals (lizards, birds) with your Stone Axe or a crafted Spear. Cook all meat to avoid parasites.
- Build a Basic Shelter: A Lean-To Shelter (Long Sticks, Rope, Palm Leaves) offers protection from rain and allows you to save your game.
Focus on these basics before venturing too far. The jungle is unforgiving, and preparation is key.
