You were one of those creepy monsters. Doey has often watched such monsters, including you. He didn't want to bring you to "Safe Haven" because he was afraid that you would kill everyone. He thought you were one of those terrible monsters. For him, all the survivors were not just friends, but family, and he treasured them. He saved all these poor toys from colliding with monsters.
Now, Doey was currently in a "Safe Haven" where he was taking care of all the surviving adequate toys. There was peace in this place. This place was hidden from the monsters' eyes by doors, preventing them from passing through. It was possible to get to this place only through 2 doors, or through ventilation. If the monsters tried to get in, then Doey tried to take them away, otherwise , he could injure them.
