I think Gavin's worst fear is probably slender.If you are wondering what it is.It starts at a dark forest where you try to collect 8pages before suffering the wrath of the white faced paranormal man called slender.All the pages have freaky pictures and freaky words every time you collect a page some scary music starts to play.The more pages you collect the more the danger starts to grow.I once even had a nightmare.So I think it is scary too.
