Removing headliner fasteners

I didn't have any luck trying to find an answer to my question in the forums so I was hoping somebody may be able to help me out. I'm trying to remove the 3 plastic fasteners in the headliner near the rear hatch. They are in there really tight so before i destroy them trying to pry them out does anybody know of a better way to do it?

 

I believe there is a specific tool to pry those out... kinda like a 2 pronged fork made out of plastic. The fasteners are tapered and ribbed and pushed into the female end which makes make them snug.
