Coast Zone

The **Coast Zone** is the southern inner zone of Patchlantis, accessible after unlocking the south exit from the base camp. It has five sub-zones, including the Sea Floor, more than any other zone.

Styral, Seabra, Seabro, Muktopus, and Galvangler are native to the Coast Zone, though all can also be found in other zones. Borka can only be found in this zone, despite not being native to it. There are sixteen Coast Zone patch pins.

The Coast Zone is connected to the Jungle Zone, Desert Zone, and Glacier Zone, as well as the Swamp Zone and Crystal Zone though the Sea Floor.

## Overview

The Coast Zone is themed after a set of shallow coastal tide pools, filled with many corals, algae, and dangerous sea critters.

### Base zone

The base Coast zone is a sandy, lush beach. Much of the terrain is covered in soaking water pools, rushing soaking rapids, and tangling sinkweed. On occasion, Soaking rain may fall across corridors.

The Sponge miniboss may be found in the base Coast zone.

### Jagged Falls

The Jagged Falls (marked on the map with a white outline) are found in the west of the Coast Zone. There is not much challenging in when it comes to plants, but traversing the Jagged Falls upwards can be difficult. The region is covered in rushing soaking rapids, pools of soaking water, and patches of tangling sinkweed. The region also has a constant stream of soaking droplets raining down from above and the sides of the corridors. Unlike most of the Coast Zone, this sub-zone has brown muddy ground that is shared with the Prickly Tidepool.

Some battle rooms in this sub-zone will interperce waves of monsters with torrential rainfall. These involve waves of Soaking water falling from overhead.

### Sinking Tidepool

The Sinking Tidepool (marked on the map with a green outline) is found in the north of the Coast Zone. It looks much more like a kelp forest look, with patches of green sinkweed on the ground that slow traversal, along with a variety of greener plants. Slippery bubbles may drift across corridors.

### Flooded Tidepool

The Flooded Tidepool (marked on the map with a blue outline) is found in the west of the Coast Zone, connecting it to the Jungle Zone. Its main source of difficulty is the fact that almost the entirety of the sub-zone is covered in soaking water, making travel hard without a proper sea mount. On occasion, Soaking rain may fall across corridors.

The Sponge miniboss may occasionally be found here.

### Prickly Tidepool

The Prickly Tidepool (marked on the map with a dark pink outline) is found in the east of the Coast Zone, connecting it to the Desert Zone. The ground is covered in dry, prickly thistles that damage the player. This biome has a red color scheme, going against the blues of the rest of the Coast Zone.

### Sea Floor

The Sea Floor is a secret zone, located underwater and accessible via a whirlpool from behind the Crab Shrine. It is considered a part of the Coast Zone but functions very differently from it.

On the Sea Floor, the player and all monsters are swimming underwater. Movement is more floaty and bullets travel slower. Some of the pins in the Undersea are unique, and some monsters are very rarely found elsewhere. Otherwise, the terrain in the Sea Floor is very similar to that of the base Coast Zone, with tangling sinkweed and scratchy thistles, as well as a variety of hostile critters.

The Borka pursuer can only be found in this zone. The Leviathan Lair in the west of the Sea Floor is the only place where it can be caught.

### Notable locations

* The Crab Shrine dungeon in the base zone contains the Crab Idol guarded by a Jumbo Kragnet.
	+ Clearing the shrine opens up the Southern Speedway shortcut in the northern part of the zone.
* The Whirlpool near the Crab Shrine leads to the Glacier and Crystal Zones via the Sea Floor.
* The Sponge microboss can spawn in the base zone and the Flooded Tidepool sub-zone.
* The Hydroventus miniboss is found on the Sea Floor on the path to the Glacier Zone. It drops the Bubble Vase treasure when defeated.
* The Borka pursuer boss can only be fought and mounted in the Leviathan Lair of the Sea Floor. It drops the Stellar Brooch treasure.
* A shortcut cavern to the Glacier Zone appears in the Flooded Tidepool after clearing the Brickloo.
* The Shining Speedway shortcut becomes available after clearing the Starlit Cavern in the Crystal Zone.

### Critters

* Frogs can be found in the base zone and all of the tidepools.
* Jellyfish can be found in the base zone, the tidepools, and on the Sea Floor.
* Sardines and Starfish live on the Sea Floor.

### Ambient hazards

* Pools and rivers of soaking water and rapids are common across the entire zone besides the Sea Floor.
	+ The Flooded Tidepool is almost entirely flooded with soaking water.
* Patches of tangling, slowing sinkweed are found in the base zone, the Jagged Falls, and on the Sea Floor, and cover much of the Sinking Tidepool.
* Dry, prickly thistles are found in the Prickly Tidepool and on the Sea Floor.
* Soaking rain may fall across corridors in the base zone and Flooded Tidepool.
* Soaking water jets may spray across corridors in the Jagged Falls.
* Small slippery bubbles may drift across corridors in the Sinking and Prickly Tidepools, as well as on the Sea Floor.
* Large slippery bubbles may drift across corridors on the Sea Floor.
* Rain pressure plates summon a wave of soaking rain from the sky. They are found in corridors of the base zone.
* Bouncy pressure plates bounce the player around. They are found in corridors of the Jagged Falls.
* Monster pressure plates summon a small monster when stepped on. They are found in corridors of the Sinking Tidepool.
* Wall pressure plates summon temporary walls when stepped on. They are found in corridors of the Flooded Tidepool.
* Arrow pressure plates summon a formation of downwards-flying arrows when stepped on. They are found in corridors of the Prickly Tidepool.

## Lore

* The Coast Zone lorestone details its origin:

> *Our bravest plunge into the deep sea. By drawing its bounties to the Coast above, we feed even the oldest among us.*

This indicates that the ancient civilization used the resources of the Coast Zone as a source of food.
