    To earn this achievement you need to destroy all 30 collectibles (15 joker teeth, 10 balloons and 5 jack in the boxes). To destroy a jack in the box, press cn_A while near it. To destroy balloons or teeth, choose the batarang with cn_down and throw it at the collectible. To track your progress, check the bottom-left corner of your map. You can earn them in freeroam after completing the DLC. Credit to PowerPyx for the videos!

    zZombieCatI experienced the same glitch as Malboa77, only seemed to be the teeth missing though. Restarting the dlc fixed it you don't have to play much to get the collectibles just don't accidentally go into a hostage area

    Hi guys,

    As written in the other solution there are a total of 30 collectibles. It's worth noting that all of them are in the oil rig area. As soon as you are out in the open your hunt can begin.
    The first teeth are actually in the room you are leaving the inside are for the first time through the hole in the roof. He has these teeth later in this video. But since they are just on your way, why not picking them up early ;-)

    I like to grab them while I am doing the main mission so what I was looking for was a chronological guide of all the collectibles. Therefore, this guide is meant as an addition to the excellent guide and videos from

    I found this good video by DukemNukem. He gets them in chronological order.

    Hope this helps you guys :-)
