Mire-Maw Engulfer

Towering plant-beasts that lie half-buried in swamp muck, their bodies disguised as mounds of reeds and rotting vines. When prey steps close, the whole mass comes alive, splitting open into writhing maws that drag victims under. Inside, the creature's core burns hot, digesting whatever it swallows in slow, hissing pain. After a kill, it sinks back into the mire, leaving only bubbles and bones.
