Lunar Grotto
Exclusive to: 
The Lunar Grotto is a Caves Biome exclusive to Don't Starve Together, introduced in Return of Them. It naturally occurs next to a Blue Mushtree Forest within the Caves, and always connects to the Ancient Archive. Moon Glass structures known as Vitreoases and Small Vitreoases are common in the Lunar Grotto, appearing alongside flora such as Light Flowers and Lunar Mushtrees on Mutated Fungal Turf.
Players will have their Sanity replaced with Enlightenment throughout the entire biome, just like the Lunar Island on the Surface.
A variety of Mobs appear within the Lunar Grotto. Mush Gnomes occasionally sprout out of the ground, Bulbous Lightbugs spawn from picked Light Flowers, and Carrats fall from the ceiling during Earthquakes. While exploring, hostile Naked Mole Bats may fall from the ceiling.
After the Archive Switch within the Ancient Archives has been activated, Greater Gestalts and Shadow Creatures from Nightmare Ramparts will continuously spawn on the edge of the biome bordering the Blue Mushtree Forest, fighting each other.
Earthquakes will drop Rocks, Flint, Moon Glass, Naked Mole Bats, Carrats, and Stone Fruit with a 20% chance each.
Tips
- Wearing the Bone Helm prevents attacks from the many Shadow Creatures that appear after the Archive Switch was activated.
- Greater Gestalts attack any player who has a Dark Sword, Night Armor or a fueled Alarming Clock equipped.
Trivia
- The Lunar Grotto was introduced in the Forgotten Knowledge update.
- For some retrofitted worlds, the Lunar Grotto is separated from the rest of the cave and players must use a Worm Hole situated in a Blue Mushtree Forest to get into the biome. This worm hole does not drain sanity when traversed.
