Worm Grass

Worm Grass is a stationary hostile creature found in patches across a few of the game's lower western Regions. It cannot be harmed or killed, and must be avoided if the player wishes to get past it.

Appearance
A strand of Worm Grass is oval in shape, with a rounded tip and a bright blue eye-mouth, which opens when alerted, and is used to attach onto and drag prey underground. Its length depends on the position within a patch - generally, the longest strands are in the middle, while shorter ones are closer to the edges. Its color depends on length - short Worm Grass is black, while longer strands tend to take on a deep red.

Abilities & Behavior
When alerted, Worm Grass will stretch towards potential prey in an attempt to grab it. If successful, they'll limit the creature's mobility, before eventually killing it. Worm Grass can be split into two varieties according to its size and properties:

Black Worm Grass
This variety can be found in small patches in, , and. While it isn't particularly strong, and the can run through it with ease, staying in it for even just a few seconds will make the grip too strong to overcome, leading to death. Black Worm Grass can also be avoided indefinitely by running and jumping to break existing strand attachments.

Red Worm Grass
Exclusive to the large swaths of Worm Grass found in the Farm Arrays, this variety is far stronger and bigger than its black counterpart. Riding a is the safest way of getting across, as any creature that happens to fall into a patch will be consumed near instantly. It is possible to break existing attachments, however this method is risky and only works with a few red strands at a time.

Trivia

 * and s are immune to Worm Grass.
 * Worm Grass hunts by sight and is insensitive to sound and movement. This does not give the player much of an advantage against the grass, but it can be used to detect creatures off-screen. Rain Deer are easily spotted by Worm Grass from far away, and by judging the grass' reaction over time, the player can determine which direction they are walking.
 * Due to a rendering error, some patches of Worm Grass in the Farm Arrays can appear white.
 * Red Worm Grass is capable of swiftly consuming some of the largest creatures in the game, including, s, and even s.
 * s, s, and s hover above Red Worm Grass instead of getting pulled into it. This interaction is likely unintended and a bug.
 * Worm Grass is highly lethal towards s, s, and s, and will kill them almost instantly, even while they're held by the Slugcat.
 * Hazers that have been killed by Worm Grass often have broken physics, causing them to phase through surfaces when dropped.
 * If a creature is held for long enough by one or more of the strands without being pulled underground, it is instantly killed.
