What are the most efficient ways to find hidden outdoor elements in Little Alchemy 2?

In Little Alchemy 2, finding hidden outdoor elements can be a fun and rewarding challenge. These elements are often unlocked through specific combinations or by exploring less obvious pathways. Here are some efficient ways to discover hidden outdoor elements:

---

1. Experiment with Nature-Based Combinations
Many hidden outdoor elements are tied to natural phenomena or outdoor environments. Try combining elements related to weather, landscapes, or ecosystems. For example:
- Rain + Mountain = River
- Earth + Rain = Plant
- Plant + Time = Tree
- Tree + Tree = Forest

---

2. Use the "Outdoor" Category as a Guide
The game categorizes elements, and the "Outdoor" category is a great place to start. Look for elements like Sky, Sun, Cloud, Mountain, or Grass, and experiment with combining them. For example:
- Cloud + Water = Rain
- Sun + Plant = Sunflower
- Grass + Fire = Ash

3. Explore Weather-Related Elements
Weather is a key theme for outdoor elements. Combine weather-related items like Rain, Snow, Wind, and Storm with other outdoor elements to unlock hidden content. For example:
- Rain + Earth = Plant
- Snow + Mountain = Glacier
- Wind + Dust = Sandstorm

4. Combine Elements with "Time"
Some outdoor elements require time to develop. Use the Time element to unlock hidden outdoor elements. For example:
- Plant + Time = Tree
- Tree + Time = Wood
- Wood + Time = Coal

---

5. Experiment with Less Obvious Combinations
Sometimes, hidden outdoor elements require creative thinking. Try combining seemingly unrelated elements to discover new outdoor items. For example:
- Fire + Mountain = Volcano
- Water + Earth = Mud
- Mud + Fire = Brick

6. Use the Hints System
If you're stuck, the in-game hints system can guide you toward hidden outdoor elements. It provides clues about possible combinations, helping you uncover elements you might not have thought of.

7. Check the Encyclopedia
The game's encyclopedia lists all discovered elements and their categories. Use it to track your progress and identify gaps in your outdoor collection. This can help you focus on specific combinations you haven't tried yet.

8. Look for Hidden Gems
Some outdoor elements are hidden behind more complex chains. For example:
- Plant + Tool = Garden
- Garden + House = Farm
- Farm + Animal = Livestock

By following these steps and experimenting with combinations, you'll efficiently uncover hidden outdoor elements in Little Alchemy 2. Remember, creativity and persistence are key!
