Okay so this movie used to be in block buster when I was little. So probably around mid 2000’s this was a thing. I remember there was this group a kid boys and they had this little shack type hideout that they used to spy but not in a creepy way, just like they acted like spies. Then this group a girls the same age, (the leader of this mean little girl group was blonde) would always try and figure out what the boys were doing. Then they came out with a second movie, and the kids were like in rock canyons or desert area cuz the mean girl got scared by a rattle snake.
