Firefly in a Bottle

The Firefly in a Bottle is a low light producing item that can be placed on ceilings, like Chinese Lanterns or any of the Chandeliers. This item is also a valid light source for purposes of NPC housing despite its low light level. The sprite is animated, and the firefly flies around inside endlessly.

It is crafted from a Firefly, which can be caught using a Bug Net at night on the surface.
