There are dolls you can unlock

I only have 3 out of 5 but Im running back through the game to get the rest

1. Frog--Act 1 defeat the haven soldiers without killing one, I used the traq pistol

2.Laughing octupus doll- You get this one by beating her non-leathel, on a bed before you kill beauity

3.Crying wolf doll

4.Screaming mantis

5. Mantis doll. After you beat mantis before you kill the beauty you have to go to the north door.

Oka, Im updating this as I go around the second time... trying for no kills getting a little hard
