Batman: Arkham Knight – Batgirl: A Matter of Family Joker Teeth
How to find missing Joker Teeth?: In-game you can recognize them as those wind-up clapping teeth toys that move around on the ground at all times.
You can find these both during the Batgirl DLC storyline and after during free roaming. While they aren’t marked on the map, you can easily find them in the outside areas (never inside buildings) by switching to Detective Vision.
Tip: Use the Batarang to destroy Joker Teeth.
Does the game save each Joker Teeth you collect?: Yes, the game will automatically save the Joker Teeth you just found, so you don’t have to play to the end of a mission. If after finding / destroying a collectible you want to stop playing the game, it’s always recommended you save before you quit so you never risk losing your collectibles progress.
