Not all statues are creepy, soul sucking monsters but most of them are. Find a place with multiple humanoid statues. If there isn't one near you, do a happy dance, and then look for groups of statues online.
If these people-like-things are trapped in these positions forever and ever, what are they saying to one another?
Write about their conversation wither from the perspective of a voyeur (possibly you) or from one statue to another.
