A Fantasy should look nothing like a Caatinga. They are completely different species and do not look like Cranwelli or Cornuta which is what your frog is produced by. I have two young Juvenile Caatingas and they do not resemble any of the other species other than having the horns above the eyes. Now if you were to have a Green Apple Pacman which is a cross between a Cranwelli and a Caatinga then it would resemble one of these frogs and not a Cornuta.skull structure is slightly different between Cranwelli and Caatinga and completely different from Cornuta. Color wise it is possible for your frog to be similar, but not in build and bone structure.
