@Thepsicho The whole thing is supposed to be a play. Making fun of harpyst means that they had a harpist, but were making fun of them (duh) then the harpist got mad and wanted to leave, so they had to beg her to stay. The lost tree probably means part of the stage set (a tree) went missing, and they needed to find it.
Lenke, Slender is based off of the Slenderman. His name is Slenderman. You can't shoot him. You can't survive him. He is immortal. He will kill you for giving such a bad image for him.
this slenderman is based on the game "slender" so I call him slender! -.-! You can kill him... but maybe he come back(?
