(Muddled) Swamp Creeper Murluk

Lore
Murluk could not discern what sort of entity had given him the gift of life for they had vanished soon after his birth. Moreover, his shifting, sagging form either frightened or repulsed the occasional human traveler who witnessed him, denying him so much as the opportunity for communication. Such reactions did not quell his curiosity, and so one day he decided to follow one.
