I would like to help ye', but I can only view the one picture. It has nothing to do with an error with the links, it is just that this device I am using is quite lame with ad.fly.
Anyway, it seems to me like the grass it a retexture. I believe the version of FeralHeart they are using is Feralistic which is no longer around. I do not believe that you will be able to find the grass anywhere I apoligize for any inconvenience this may cause.
