Void Worm

Void Worms are gigantic lengthy creatures that reside deep within the Void Sea, underneath the Depths of Rain World. These are the only sign of organic semi sentient creatures that are encountered in a vacant area. Despite their sheer size and the absence of fins or any bodily functions in order to achieve sharp and quick maneuvers in an ocean like environment.

Appearance
Voids worms have silvery bodies that incomprehensibly stretch to a gargantuan size with features of reddish-brown colors under their leviathan body, but particularly small heads compared to their body ratio with golden eyes and antennae-like limbs with hooks on the end connected to the end of their long bodies. They can be encountered in the Ascension endings for all s. Although the player only encounters one Void Worm that actively interacts with it, there are many others that can be seen and swum past. Slugcat is forcefully moved in the same direction as a Void Worm when its body passes directly overhead, accompanied by a loud rumbling sound.

Encounter
In the Depths, when Slugcat jumps into the void fluid, swimming down long enough you will see many void worms together swimming aimlessly near each other. Some void worms nearby can interreact indirectly towards Slugcat by propelling them in the direction they're heading, either beneficially or preventing towards Slugcat goals. Swimming below the void worms swarm causes a Void Worm to appear with a unique rumbling sound. After a few moments of inspection and examination, if the creature is deemed worthy enough, it "hooks" Slugcat with a string, and then pulls the Slugcat upwards, then back to the depths of the Void Sea diving down promptly towards Slugcat destination of ascending, aiding in speeding up the process of swimming downwards before releasing Slugcat and vanishing. Upon being released, Slugcat is left in a pitch-black abyss with only a white light and music to follow to the ending of the game.

Trivia

 * In versions of the game earlier than 1.5 it was possible to be killed via fall damage from an invisible Void Worm in the room before the void sea.
