Freeze!

You are unsure if you can unfreeze a group that large, but attempt it anyways.

It works, surprisingly, and all five girls are frozen. You take the girl in the middle and bring her back to your group. They are oblivious to the new girl. Meaning that people who are frozen in time are temporarily forgotten by society.

You also decide that this place could use some entertainment, so you turn to the four other frozen girls.
