After watching this video with Sweetiebelle's voice actress playing Slender, I had to draw this. x'D
( She begins to talk in her SweetieBelle voice at 7:42 ) WARNING: No great sound quality, so you miiiight wanna turn down the volume just a teensy bit.
EDIT: will add the glow on her horn later.
New EDIT: Fixed! Glow's on.
New new EDIT: GREEN glow, there!
