One of the hidden trophies/achievements in Batgirl: A Matter of Family (the new Batman: Arkham Knight expansion) is called All Snug in Their Beds. To unlock this trophy/achievement, you must uncover the hidden history of Seagate Amusement Park, which is done by obtaining five voice recordings. Finding the locations of these recordings is actually pretty simple. Scanning the environment using Detective Vision will make the voice boxes glow orange, even at a distance. But, it isn’t a matter of just locating the recordings. Players must complete four challenges in the form of carnival games.
The order in which you complete the challenges doesn’t seem to matter, so complete them as you pass them or follow the order of this guide if you’d like. The fifth recording is located behind a locked door that will only open after obtaining the previous four. You’ll know that you collected all four if there are four green lights lit up on the map beside the locked door.
