Fauna and flora | Caves Don't Starve Guide

In caves you will encounter well-known creatures, such as: Spiders, Tentacles, and Fireflies. You can also meet there Cave Spiders. Their main feature is their shell where they hide themselves, thus minimizing the receiving damage. They live in Spilagmites, which can be destroyed e.g. with an axe. Note though, that Spilagmites are rebuilt upon re-entering the cave. Along with spiders there are also Spitters. They spit web-projectiles, so watch out for them.

Spiders drop meat when killed.

Batilisks were already described above. You will also meet Bunnymen. If your sanity is too low, they transform into Beardlords, who drop Beard Hair and Meat when killed. Slurtle/Snurtle are neutral mobs who can hide themselves in their shell. They drop Broken Shell and Slultre Slime. They live in rock mounds, which can be destroyed.

Slurtles have high health.

While spelunking, you can also meet neutral Rock Lobsters. They eat gold, flint, and rocks. Slumonkeys are neutral too. They live in Barrels where they hide when their health is low. They also do that during earthquakes. Big Tentacle is larger than the one living on the surface. When its health is low, it retreats into its hole, causing an earthquake. Watch out for Charlie (Grue, Night Monster) - he attacks when it's dark.

Big Tentacle is a real threat.

Other new creatures:

- Clockwork Castle - very strong; can be met near the Maxwell's Wooden Things

- Lureplant - it uses Leafy Meat as a decoy; it can spawn Eyeplants, which will attack you

- Pengull - it lays eggs, and hides them from you. This may cause the eggs to became Rotten Eggs. Pengulls produce Manure.

Just like on the surface there are plants growing underground, such as Mushrooms and Saplings. However, Light Flower, which is a light source, can only be found underground. It produces Light Bulb. When picked, Light Bulb will regenerate after a while and then it can be picked again. Mush Tree is a light source; chopping it down produces a Log and a Blue Cap. A Stump can be dug out with a shovel for an extra log. The most common trees are evergreens. Burning them produces Ash and Charcoal. These trees do not grow back.

As you see, you can bump into more than one tree at the same place.

Cave Banana Tree grows only in the caves. You can chop it down and get 2 Twigs and 1 Log. A Stump can be dug out with a shovel (1 extra log). You can eat bananas just like a Splumonkey does. Bananas regenerate. Shatter Stalagmites with a pickaxe to find rocks, gold, flint, and occasionally gems. You will also come across Lava Pits. Using a Hammer on a lava pit will cause it to glow for a while. Use the hammer again, when it goes off. Yellow and Orange Gems can only be found in the caves. The best chance of finding them is right after an earthquake. You can also try your luck crushing stalagmites - but this is rather rare.
