Overview[]
The Walking Lamp (also known as Raitou-Oka by some fans) is an effect NPC that consists of a small lamp with feet which can be found in Lamp World, which is a part of the overarching Number World. By interacting with it, Madotsuki receives the Lamp effect.
Interaction[]
As previously mentioned, the Walking Lamp is most noticeable for providing the player with the Lamp effect, although it can be hard to track down amongst the repeating lamps of the world it inhabits. It shows standard reactions to the Cat and Stoplight effects, but curiously flees twice as fast when the Knife is held. Otherwise, it can be stabbed and killed as normal.
