A hobgoblin is a make-believe creature that is often shown in stories as a mischievous and tricky creature that looks very similar to a human. Hobgoblins are not real and only exist in stories and games. They are often shown as having pointy ears, a long nose, and short, hairy bodies. Think of them like a friend dressed up in a Halloween costume.
Some people believe that hobgoblins come into people's homes at night and cause trouble, like hiding things, making noise, or breaking things. This is just a part of the story, and it is not true in real life.
Overall, hobgoblins are just a fun imaginary creature that people like to talk about and use in stories and games. They are not real, and you don't need to be scared of them.
