Sanity Killer

You pick the locks easily. They snap right off with a simple turn, like a toy. You realize the chains ARE a toy. In fact, you appear to be in a dollhouse! You hear someone walking down the hallway to check up on you. Apparently you are in the dollhouse in the playroom of this building, and have shrinked! But enough of that, someone is coming! Light footsteps... could it be barbie?
