Plains
Open land for a camp. Plains contain rare trees, apple trees, bushes, rabbit burrows and small ground details.
GUIDE 05
The world
Every biome has its own resources, wildlife and reasons to keep exploring.
CURRENT BIOMES
The surface regions
Forests
Forests have more trees and bushes. Find normal or poisonous mushrooms, rare stumps, rabbit burrows, foxes and boars.
Sakura woods
A lighter woodland with its own trees. Sakura and willow seeds let you bring this atmosphere back to camp.
Lakes and shores
Fill an empty bottle on a shore and fish for eight species. Collected water must be purified at a campfire before it is safe.
Mountains
Movement is slower. Mountain rocks provide copper, while cave entrances lead to iron ore underground.
RARE DETAILS
What exploration reveals
Stumps stay intentionally rare: their roll is 0.6% per eligible plains or forest tile. large fallen tree stump uses that same roll, then appears on 20% of stumps (the two earlier models keep 48% and 32%). It does not increase the overall stump frequency. Apple trees are also uncommon plains discoveries, with a 4% chance among eligible tree tiles.
Burrows can hold up to three rabbits. After a full hunt, the population returns after three days. Foxes usually flee from the player; boars can charge when provoked.
The desert is not generated in the current release. It remains in the game's data for later work, but playable worlds currently use plains, forests, sakura woods, lakes, shores, mountains and caves.
GO OUT AND RETURN
Prepare every expedition
Take food and water, bring a pickaxe for copper or caves, carry several torches for the dark and watch the clock. A maintained camp is the best reason to return before night.
Forest plants and rarer burrows
Look for yarrow in forests, including previously explored areas: harvest one bare-handed to collect one yarrow for bandages. Rabbit burrows now have a 0.4% candidate chance on eligible plains tiles and 0.2% in forests, reduced from 0.6% and 0.3%. Burrows must be at least 7 tiles apart, so the actual density is lower than the raw roll. These rules also apply to older worlds.
On lake shores, look for bubbles and ripples before fishing. Underground, caves now have 3 or 5 rooms, lava slimes and a final chest. Consult the fishing and cave guides before setting out.
Harvesting surprises
Harvesting a normal or golden berry bush has a 1 in 50 chance of startling a fox. It immediately runs away, in any biome.
When a tree is completely felled with an axe, a hidden bird may fly out of its canopy. The roll is 1 in 15, once per tree, not once per axe hit. This harmless event can happen from day one and gives no loot.
An eligible tree may also hide an angry squirrel (a 1 in 45 roll). It only appears when the tree is destroyed, pauses briefly, throws three acorns and then flees. Each hit deals 3 damage; move to dodge the projectiles. It does not appear in trees reserved for birds or wasp nests.
Felling a tree can also disturb a wasp nest. Wasps pursue you for 15 seconds before leaving; the nest disappearing does not end the chase.
Search abandoned camps
An abandoned camp chest contains 2 base bandages. With no blueprints learned, its extra roll gives any blueprint with 35% total probability, a stone pickaxe with 15%, or no extra with 50%. Known blueprints change these weights; see the blueprint guide. An emptied chest does not refill when you reconnect.
Two morning boars
From day 10, two boars may settle near a campfire at dawn: one roll per morning, with a 2% chance, or 8% on a full-moon day. They require accessible space around camp; spawning can be cancelled if no safe location is available.
They appear about 15 tiles from the fire, roam freely and may occasionally approach to around 4 tiles if terrain permits. Getting too close or attacking one can provoke the pair. A badly injured boar flees. They leave after four days; reopening a save does not reroll the same morning.
Rain and thunderstorms
Continuous rain ambience gradually follows rain intensity and respects audio settings and pause. Falling drops produce small ground splashes and water ripples; roof-covered surfaces are sheltered.
On the surface, a brief lightning flash precedes thunder by 2–3 seconds, including on full-moon nights. These effects do not change weather frequency or survival rules.
Surface ruins to discover
Small ruins, medium groups and very rare immense sites appear in forests, plains, sakura woods and mountains. Not every ruin has a chest. Large sites scatter chests across different wings; visual families and mirrored pieces vary the layout.
Abandoned camps, ruins and secret chests are not automatically marked on the map. In older saves, explore new regions: previously discovered areas and buildings are protected against new ruins appearing over them. Detailed site and loot guide.
