Overview
The Alley Demon is an NPC that appears in The Sewers.
This creature is composed of a very dark blue mass with a dark blue-green face and black eyes, each with a red pixel for a pupil. It is found before reaching Big Red.
Interaction
The Alley Demon roams within the lane that the player cannot access without hacking, so interaction is normally impossible. Nonetheless, it displays normal reactions to the Cat and Stoplight effects, but not the Knife effect.
