According to Bulgarian myths, dwarves – first settled on Earth. Then the giants came. The giants, Ispolins, lived in the mountains. Some had three heads, but only one eye on the forehead. Some had one leg. They lived in mountain caves and ate only raw meat. He loved the dragon meat, so the dragons were the greatest enemies of Ispolins.
Still, the Ispolins had a very strong voice and could easily talk to each other while standing on top of the mountains. The giants were not afraid of the dragons and other, but they were afraid of.. blackberries. Because the spiked blackberry bushes in the swampy places, would trap the Ispolins and they could not escape and eventually would die.
It’s not easy to see Ispolins these days, because there are no blackberry bushes in swamps left.
