Well, I did not make my self clear. Yes, let's forget about the "minigame" part. What I really meant was that kids get lost and we receive a notification about it. Something like this:
Alert! Little Tim just get lost and his parents are looking for him, if you see him, please notify the authorities. He is about 8 years old, brown hear, short pants and red shirt.
Then, we could go and look throughout our parks for a kid screaming and crying, pick him up with our cursor and take him to where his parents are or to the nearest safety station.
This would be totally optional and in park's stats would say, Found kids today: 7
