Wemmuth

[The wemmuth was one of the monsters original to Pathfinder 2e's first Bestiary, but it had to wait until Monster Core 2 to get a conversion to the "remastered" rule set. Not that there's any difference between the stats than removing the alignment and adding a saving throw to the thorny defense ability. I wish they had changed the art; the headless humanoid configuration depicted is not as interesting to me as the massive tumbleweed described. I wrote up the jubokko, a yokai with a very similar origin, way back in the "Year of Yokai" before there was a separate Creature Codex. I linked the two monsters in my flavor text.

Wemmuth CR 15 NE Plant This mass of vegetation resembles a tumbleweed the size of an elephant with earth, stones and scraps of broken armor integrated into its mass. Thorny tendrils lash out around it, probing for new victims.
Plants grow uneasily in places where vast quantities of blood are spilled. They can develop a taste for it. One of the creatures that may form on a battlefield, around a city under siege, or over a mass grave is the wemmuth, a vile conglomeration of vines. Like their metaphysical relative the jubokko, wemmuths hunt living prey to slake their thirst for blood, preferably humanoids. Wemmuths are more mobile and decidedly more intelligent, however, and are better able to disguise themselves as different kinds of mundane vegetation instead of being limited to the form of a tree.
The form of a wemmuth is a vast network of thorny vines, which would stretch for more than a mile if laid end to end. They instead form their bodies into knotty spheres, often incorporating masses of earth and stone. Not only do these assist in camouflage, the wemmuth can lob rocks like a catapult at enemies who keep their distance or attempt to flee. In combat, a wemmuth simply rolls over smaller prey, while grabbing at larger morsels with its tendrils and squeezing them dry. A wemmuth can heal rapidly by drinking blood as it battles, and enemies that attempt to engage one of these creatures without access to cold damage may find themselves losing a war of attrition.
Wemmuths are disconcertingly common in war-torn areas, and oftentimes opposing armies will accuse the other of sowing wemmuths intentionally as a form of maintaining a no-mans-land. The actions of demons, devils or other fiends is also sometimes invoked. The truth of the matter is, wemmuths commonly grow without any assistance, and rarely have allegiance to anything other than their own hunger. Wemmuths understand the languages of the fey, which has led sages to hypothesize that the first wemmuths were “prototypes” of carnivorous plants growing in the First World. Evil fey or druids sometimes “domesticate” a wemmuth to serve as a guardian, but this requires ample use of plant controlling magic, or else the wemmuth will wander off as soon as it gets hungry.
