Haunted lamps flicker in alluring ways to attract mates. They typically lay only one or two bulbs at a time and guard them fiercely due to both their fragility and small numbers. A bulb eventually hatches into a spooky Halloween nightlight. This process has never been witnessed, and thus is not very well understood. The nightlights are entirely dependent on their outlets, and must still rely on the protection of their parents to survive. Only until they grow into their juvenile state, table lamps, can they leave their parents to explore their surroundings and find their first lampshade. Like hermit crabs, lamps must replace their shades periodically as they reach their adult state, the floor lamp.
