Where did GoblinKnees come from?

At the dawn of time, God realized he needed to create balance between man, and beast. So he created what us humans know as "Goblins". after millions of years after the first goblin was born, hunters realized something special about the goblins, their knees. their knees were strong and powerful, like vibranium but a just a little weaker and less rare at the time. the hunters hunted down the goblins, killing them for their knees. this caused their species to go into near extinction which forced governments to make it illegal to hunt or kill these creatures. Alas, people still killed these animals making them rarer and rarer to come upon. now, after millions of more years later, people assumed them to be gone forever but goblins have been appearing in rare sightings only making them more mysterious and creating parties to search for these elusive beasts. now humans do not need goblin knees as a strong resources and admire these creatures from afar. people have also spotted goblins wearing articles of clothing and to have appeared with no mouth.

Amateur sketch of goblin spotted in Forrest in Colorado that appears to have  no mouth and is wearing what seems to be a hat.
