I don't remember the names of the characters, but the one on the far right, you can see through her skirt when the light is on behind her, and she doesn't have 'thighs'...
From left to right: Dook, Fatz, Beach Bear and Mitzi. And of course she doesn't have thighs. If they were never meant to be seen (this is a retrofit, her original skirt doesn't let you see through it), why wasting materials on them?
Love the rockafire explosion, used to see them at chuckie cheese and I think a place called circus pizza or Piccadilly circus pizza? Something like that. Either way as a kid, pulling the curtain and looking at the characters used to scare the crap of me as it seemed their eyes were wide open and it seemed they'd be staring through your soul. Never seen five nights at Freddy's but I'm pretty sure it's the same premise. Demonic inanimate objects coming to life?
