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 final release.

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.



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.



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 Outskirts. Some rooms of Suburban were scrapped, while others were re-used in different regions. Outskirts is still referred to as "SU" in game-files.
