Batgirl: A Matter of Family is the brand new expansion to Batman: Arkham Knight that puts players into the shoes of Batgirl before the events of Arkham Asylum. Set in Seagate Amusement Park, players will have to navigate the different attractions while endeavoring to save some unlucky hostages. Also scattered around the world are three different types of collectibles that, when gathered, will earn you the A Blade of Memory trophy/achievement.
Here are the locations for all 15 Joker Teeth. Head to the location indicated in each image and, if facing in the same direction in the image, the teeth should be right in front of you. Activating your Detective Vision will make them glow yellow, and they also have an audible chattering that can be heard once you’re in the area.
