The being known only as Luunshee is a phantom of expansive form. Although seemingly mute they are able to perceive basic human speech. Their hide has a texture between rubber and dry paint.
[A]
Their demeanor is often friendly, with the occasional impish act, and only angered or saddened by the mood of a nearby friend/acquaintance.
Both eyes are usually partially open, resembling circular arcs. Their mouth is often closed except while one or both eyes are closed. Eyes and mouth are both wide open only during inhaling air or surprised gasps.

[B]
On Luunshee's front is a discoloured spot, or their "navel". Although appearing flat, this navel contains a "pocket" which Luunshee can reach inside and pull out any one of various like-themed* items.

[C]
Luunshee's defining trait is its stretchy body. Their "stomach" (a space separate from its pocket, by the way) can hold a yet indeterminate volume. Inhaling can only bring Luunshee to ~____ times their usual size, though other intake methods (hydrants, hot air, food, etc.) can provide greater results.
