Loco Labyrinth Biome

Terrain

In Loco Labyrinth, the map is broken up into a dozen small irregular chunks where the map pieces would swap randomly. The boundaries of the chunks are not indicated to the players in any way visually other than when the swap occurs.

After a random interval, random chunk pieces would ramble for 5 seconds and sink into the ground, then a different piece would emerge to fill the chunk. Each chunk has 2 pieces that alternates when the swap happens.

Chunk swap does not occur and can be interrupted if the player is standing on it or if connected tracks are placed on it. In addition, the chunk the station is on does not swap either. Other than that, nothing else would prevent a chunk from swapping. This means bolts and other collectibles can be hidden by the chunk swap. Commodities and bridges can also be swapped out temporarily. Tools on the swapped chunks will respawn.

The best strategy is to allow chunk swap to occur on a bad chunk if the chunk is mostly hard walls or water, and prevent good chunks from swapping out by running on it as soon as it rambles.

NPCs

Mimictree

This monster hides among innocent trees waiting for careless travelers crossing their path.

Mimictree is an immovable hostile NPC with 8 HP. It looks like a regular tree, but you can actually tell it apart from regular trees by their circular top and darker green leaves.

When the player walks in front of it, the Mimictree will extend its tongue to attack the player. The result depends on what the player is holding.

Player holding	Result
Nothing	Player loses one life.
Tool	The tool will be taken away and respawn.
Commodities	All commodities are consumed but can be retrieved by killing the mimictree.
tracks	All tracks are consumed but can be retrieved by killing the mimictree.
Animal	The animal is eaton and killed
Dynamite	The dynamite will be consumed and explode inside the mimictree, instantly killing it. Note: if you drop the dynamite beside it, it would survive).

When the mimictree dies, it drops all items that it consumed and 1 compressed wood.

The mimic tree does not attack animals on the ground nor consume items on the ground.

Slowdown Snail

A curious kind of snail species that feeds exclusively on train tracks. Rideable and milkable.

Slowdown Snail is a non-hostile milkable animal that eats unconnected tracks on the ground. After it has consumed 6 normal tracks, 1 Brake track would be produced. Note that this is half as efficient as the Brake Track Wagon.

Boss Fight

Mothermimic

Every mimictree is a decendant of this huge specimen.

Mothermimic spawns when a chunk is swapped. When this happens, the chunk is entirely replaced by a forest that cannot be mined using regular methods.

The boss has two ways of attacking the players.

First, it will spawn a swarm of moving mimics in the forest, which can move and attack actively and randomly. Moving mimics look similar to regular mimics but the leaves are lighter, and their HP is just 1. Since moving mimics do not chase down the player, if you are careful enough when walking pass them it is possible to ignore them entirely.

Second, the boss periodically throw bombs at the player. Those bombs are not dynamites created by the Dynamite Wagon but rather look similar to the bombs created by the Versus Constructor Wagon. Those bombs have a fuse time of 5 seconds and do not deal any damage to rocks and trees. However, they can kill players and mimics. When a bomb is placed on the boss's forest, the chunk the boss is on would swap immediately, which acts as an instant kill trick.

Also note that not all chunks can spawn a boss, however chunks that can spawn the boss are not indicated to the players visually. If you see a chunk swapped and the boss hasn't spawned and the boss did not spawn with the chunk, then the chunk cannot spawn the boss.
