Monstruo en el drenaje

El usuario estaba recorriendo el drenaje y no sabe qué es lo que se encontró, si una persona tratando de jugarle una broma o una criatura extraña que ronda el área.

I went into a local sewer system today. There was either a person or something else in there. It was scary. And if it was a person why did he/she have to scream at me with a light up mask on? Like wtf from r/SirSpooks
