Beyond the thick forest lies a colossal winged flightless dragon with a unique distinct feature that is its plated tongue!
According to legend it seems to prefer diseased humans and animals that will soon be on their death bed, but would never sink its fangs into a healthy individual.
A folk song suggests it may have had myopia or even poor eyesight so it has difficulty telling if someone is in good shape or terminally ill. That's why I am guessing the trick may lie in its plated tongue which can somehow detect potential prey, much like how a snake picks up body odours from the air. One thing that's sure is that the dragon wouldn't accidentally bite its own tongue because my great grandma told me it can't say any tongue twister at all.
My question then is how does this dragon with plated tongue hunt for prey?
