I think Masky or Hoodie got tired of Toby annoying them so both of them put him in a box and stuck him in a ally...
Jeff: hey it's really quite...
Ben: yea and nothing smells like smoke or waffles...
Sally: Where's Toby he promised he would play with me!
Ej: oh yea where is Toby I haven't seen him all day!
Masky: me and Hoodie put him in a box and put him in an ally way
Slenderman: WHAT!?!
Hoodie: Aw shit...
Slenderman: YOU BETTER FIND HIM BEFORE I-
Fangirl: HEY I FOUND TOBY AND I TOOK CARE OF HIM LOVE ME!!!
Toby: Die...*cuts off girls head*
