These are the same treasures available to any character, giving a small amount of experience and a vendor-able item. WoWhead's Timeless Isle article is still very relevant for finding these and I recommend you use that article to locate which treasures will be easiest to acquire.

Note that you will only need to gather four treasures to complete this achievement.

After killing some 50 Hozen I start to doubt the key exist in Panda Remix.
