A goblin is a creature from stories and imagination. They are usually small, with pointy ears, green or brown skin, and sometimes have sharp teeth. They have a mischievous and sometimes mean personality. Some stories say they live in caves or dark places and come out at night to cause trouble. They are known for stealing things and playing tricks on people. But remember, goblins are not real and only exist in stories and games, so there's no need to be afraid of them.
