In my experience with the dreaded "green spots," your frog will either keel over and die, or be perfectly fine. My frog went through a phase of the spots, and I think it was just apart of his development as shortly after he began croaking. Nobody really knows the cause of the spots,but I would say if your frog is eating, pooping, jumping and sleeping, don't worry too much. If you are really concerned, you could get his poop tested and see if there is any parasites.
