Worm Grass

Living grass is a patch of: Living grass (obviously). Initially, they appear to look like red or black worms that stand straight up, but when a creature is near by, their tips turn blue. Upon entering their range, they will attempt to reach and grab any living thing, leaving anything within its grasp little chance of survival. Once the poor creature is killed, the carcass is immediately digested. Though you can traverse through small patches of living grass (though you want to repeatedly jump and run out of it), large patches of living grass will kill you if you make contact with them, as their grasp is stronger than smaller patches.

The only way to pass large patches of living grass is either to find a way around it or hitching a ride on rabbit walkers.
