Maworbs come in sizes ranging from as small as a softball to as large as a pickup truck. They resemble round mounds of human-like skin that appear to be mostly composed of their trademark mouth, which includes large, pillowy lips, a wide, thick tongue that can stretch to wrap around victims, and a seemingly endless throat. Maworbs typically prefer for curious victims to come to them, seducing them with the sight of their maw before softly, gently taking them in and swallowing just as gently.
