Cut Content

Given the long development time, there was bound to be some content that didn't quite make it in. This page is meant to document everything that was cut from the most recent release of the game.

Nightcat
Nightcat is a Slugcat found exclusively in arena mode from versions 1.5 to version 1.9, being removed by the Downpour DLC due to its modified handling of Arena characters. Nightcat has no campaign or special abilities and is identical to Survivor besides the color. They have dark blue skin, two white eyes, and a white nose. Since they don't appear in single player mode, they are most likely not canon to the Rain World story. The most likely reason for Nightcat's inclusion in the game was to give the arena mode a fourth Slugcat for multiplayer. All four vanilla Slugcats have the same abilities in non-Downpour Arena mode. In Rain World's DLC Downpour, the secret Slugcat,, has some similarities to, and is somewhat implied to be, Nightcat.

Makes a cameo appearance in campaign, showing up several times in the ending's slideshow.

Brain Trees
"'A brain... tree... that drips? It seems significant somehow. But not all of the mysteries of Rain World are there to be solved.'" Brain trees were large, seemingly organic growths that dripped down with a mucus-like substance. Not much information has been provided about their potential role in gameplay, but they were most likely just aesthetic background elements. However, they can still be found in Garbage Wastes in Spearmaster's campaign.



Bubbles
Bubbles (also referred to as Bubble Barnacles) were first revealed in this alpha trailer. These transparent, red orbs would trap that flew into them; after accumulating enough, a Bubble would retract into the den right below it, containing some kind of creature that creates the Bubbles, and presumably eats the Batflies they trap. Bubbles seemed to have little negative effect on the, only popping and causing knockback when touched. It's possible that this mechanic was later repurposed for s, which also produce a large pop when the Slugcat gets too close.



Mimic Beetles
Mimic Beetles were small, passive creatures, appearing throughout some of Rain World's development builds. Though not much is known about Mimic Beetles, they likely behaved similar to most Bugs. These beetles appeared to fly around in very large groups. Additionally, like s, Mimic Beetles could camouflage themselves by taking on the color of the background.



Slugcat Pups
Slugcat pups were a feature present in the early Lingo builds of the game. They couldn't defend themselves, or get around as easily as a fully grown Slugcat. Initially, the player was tasked with carrying, protecting, and feeding them. One pup could be carried at a time, and another could be lead by hand simultaneously. Pups could also carry additional or s. Green, yellow, and black pups have been featured in developer screenshots and videos, while gameplay and development ideas were discussed at length in the Rain World Devlog.

Pups were not ported over to the Unity version of the game and no publicly available builds featuring them exist. The developers have briefly discussed the difficulty they added to the game.



A completely separate implementation of s was added to the Downpour DLC, unlocked by completing Gourmand's food quest and getting one of the endings. Afterwards, slugpups will begin spawning randomly in shelters on subsequent playthroughs, where they run from the player until tamed. After sleeping with a slugpup, a set of three food pips will appear above the player's hunger bar - this is the slugpup's own separate hunger bar, flashing red when the slugpup is captured by a creature.

Light Pink Playable Slugcat
This slugcat was shown in at least two alpha videos of Rain World Gameplay, and was available contemporaneously with the Pups feature cut from the game as of the same teaser linked in the previous image; however, this Slugcat predates that video, and can be seen in the following linked public video circa 2012 showing early alpha gameplay. This slugcat is the same colour as one of the adult Slugcats in and 's intro cutscenes, and those cutscenes probably reference this Slugcat and its white partner  - the protagonists of early Lingo builds of the game - as the "parents" of the modern C# version of Rain World, especially considering the screenshot shown below and to the left, which features pups in the colour of   and  along with a blue one also shown in said cutscene.

Suburban

 * "Underground. Dirt, tunnels, pipes, bogs, sewers. Featuring more maze-like elements. It might get dark here the lower you go, and certain creatures might even glow."

Suburban was intended to be the first region of the game. Though the area wasn't included in the final release, it was an early version of what would eventually become. Some rooms of Suburban were scrapped, while others were re-used in different regions. Outskirts is still referred to as "SU" in game-files. A late version of this region, which was very close to becoming Outskirts as seen in the final game, was mapped by the community, and may be viewed here, along with four other alpha regions.
