Thatchling

The typical thatchling appears as a humanoid bundle of dry grass and twigs, held together by coils of what looks like glowing blue hair. These minor undead can't form bodies larger than those of a small human child.

In rural Shenmen, some branches of Sangpotshi warn of what can happen if a soul bound for reincarnation is prevented from entering the River of Souls and rejoining the cycle. These souls become frustrated, confused, and then furious at what they feel is a denial of the body they deserve, and in turn, they force vegetation to serve as their new body. Others theorize that when a body is buried in a shallow grave, the roots of grass growing down into the remains can tangle the soul and capture it.

Thatchlings are intelligent and capable of speaking but rarely do so—they generally have little to say to those whose lives they covet. Rarely, one might attempt to lure someone into an area of tall grass or dense undergrowth by calling out to them for aid, but they have little skill at deception, so such tactics aren't particularly effective at making them seem like actual living creatures in need of help.
