I found another spot, and I took a screenshot.
Here's how tiny they are:
I was farming on my death knight, and I use a route in Uldam that also takes me by every spot I have found the mysterious camel figurines. I like to combine prospects whenever possible. I hadn't found any in this spot before, but I had always figured it would be a great spot for one. I was actually flying over it to head back to the other 2 spots north of there, when WHOA! NPC Scan popped up the little target icon you see on my sexy map there. I actually remembered to screenshot this one! I took another without all the ui clutter, but you could barely see the figurine.
So, here's the updated map of the ones I have found (the tiny yellow dots):
Coordinates are 24.44, 59.98. (Edited because I forgot to add these at the time of post.)
Alas, still none that have brought the little fellow out that whisks you away for the mount. Perhaps next time...
