Neglectern is a large lamp-like spirit. Its body is a vaguely-conical structure, similar to a typical lampshade. The top and botom of the lamp has purple rims, which the main shade itself is cream-colored. The body has several vertical lines encircling it. Neglectern has one large eye with a crescent-shaped pupil. Neglectern has a large red tongue that floats inside the lampshade and hangs down from the bottom. There are also two purple tassles that hang down from the bottom rim; these tassles each have three pink bands. Neglectern has a large scarf-like piece of purple cloth tied around the top of the lampshade. The band has pink edges and numerous pink bands running down it. This cloth acts as an arm; there is a pink dot on its palm and there are three purple fingers.
When Neglectern's lamp is lit, Neglectern is able to leap out of its body to attack whoever lit it.
Neglectern lies in waiting until a traveler lights the lantern, whereupon it leaps out and attacks the victim. They were created when a lamp was mistreated and thrown away.
