99 Nights in the Forest is a survival Roblox game, where you need to survive 99 days in a forest from a vicious Deer and its cultists. The latest update has added a new Jungle Biome and a bunch of new features to explore around.
The update adds a new Jungle Biome, with an Ancient Temple and brand new mobs. Moreover, this is just the beginning of the update, as more content is set to arrive in this biome in future updates. So, to help you out with this update, here’s a complete guide to the Jungle Biome in 99 Nights in the Forest.
How to Reach Jungle Biome in 99 Nights in the Forest

To access the Jungle Biome in 99 Nights in the Forest, your priority is upgrading the Campfire to Level 3. The biome won’t appear first until you fully complete this upgrade, so it’s a required step before you can explore the new area during your run.
Once unlocked, you will immediately notice the shift in environment. The grass becomes noticeably darker, and dense tropical foliage with wide, lush leaves starts appearing in the area. Moreover, you will also see new mobs spawning in this new POI location.
However, don’t stop at Level 3. While exploring the Jungle Biome, you should continue upgrading your Campfire to at least Level 6 to unlock the biome’s full area. Since the Campfire upgrade acts as the main progression gate for this biome, make sure you prioritize maxing it out early if you want to reach the Jungle as quickly as possible.
Ancient Temple Location in Jungle Biome in 99 Nights in the Forest

The Ancient Temples stand tall in the Jungle Biome. They are hidden within the Jungle Biome, but its yellowish stone pyramid design with wide staircases makes it easy to recognize from afar. Because of its size and structure, it naturally stands out as the biome’s main point of interest.
The temple offers two key areas to explore. In the top area, you will find either a regular chest or a Tier 2 chest, but Jungle Cultists and boars guard this section. Make sure you defeat all nearby enemies before attempting to claim the loot to avoid dying during your run.
The underground section can be reached through stairways on one side of the temple that lead into a long corridor. Here, you must complete an obby by avoiding poison darts or parkouring across pillars. At the end, an altar holds the Crystal Skull Key, but once you take it, a wave of poison darts fires from both sides. You can also find a Tier 2 chest, which can give some decent loot.
How to Use Crystal Skull Key
The main purpose of the Crystal Skull Key is to open a secret area located inside the Ancient Temple. While you are in the Jungle Biome, you will encounter multiple Ancient Temples, each with a Crystal Skull Key, except for one. This can be recognized by a four-pillar altar at the top of the temple.
Once you have all four Crystal Skull Keys, you can place them on top of the altars. This will open up a staircase that leads down to the underground part of this Ancient Temple. Moreover, this area has one of the best loot that you can acquire for mid-game. Below, we’ve listed all the loot that can be acquired in the Ancient Temple.
- Poison Claws (new melee weapon, exclusive to Jungle Biome)
- Cultist Gem
- Gem of the Forest Fragment
- Crossbow
- Poison Spear
- Mossy Coins
- Coal
