Four kids playing around a muddy pit at Medical Lake discovered it was quicksand when a couple of them became stuck.
KXLY reports a girl and a boy became stuck Saturday in mud up to their chests.
Another boy ran for help and found developer Larry Pilcher, who was showing homes nearby. He called 911 and says it took about 20 minutes for firefighters to dig and pull out the kids.
They were slightly hypothermic, but unharmed.
