What was a mere patch of green grass suddenly uproots itself and shows its true form: a flat, turtle-like creature with a wide maw filled with sharklike wooden teeth._
Grassland Ambushers. The carnivorous sod is a plant monster that disguises itself as a simple patch of grass until it is stepped on. It then uses its grass-like tendrils to trip a creature before biting with its vicious jaws. Carnivorous sods typically prey on small herbivores, such as deer and rabbits, that come to graze on their backs, but they have been known to attack just about anything that treads on them as long as the target is Medium or smaller. Sometimes dozens of carnivorous sods gather together to hunt, though this is due more to happenstance than planning on the part of the monsters.

Traits

False Appearance. While the carnivorous sod remains motionless, it is indistinguishable from a normal patch of grass.

Spell Eater. If the carnivorous sod is in an area targeted by a spell that enhances plants in that area, such as the entangle, plant growth, and spike growth spells, the carnivorous sod absorbs the spell, ending it, and gains 10 temporary hp for each level of the spell it absorbed for 1 hour.

Tripping Grass. If the carnivorous sod didn't move on its previous turn and hits a target with its Grass Trip, it can make one attack with its bite as a bonus action.
