Okay kiddo, have you ever heard of a mythical creature called a cockatrice? It's like a mix between a chicken and a dragon.
When people talk about cockatrices, they usually mean a creature with the head of a rooster, the wings of a bat, the tail of a serpent, and the ability to turn people to stone with just one look.
Now, I know that sounds scary, but don't worry, cockatrices are just made up stories. They aren't real. But they were really popular in medieval times as a way to scare people and tell exciting stories.
So, if you ever hear someone talk about a cockatrice, just remember that it's a mythical creature from a long time ago that people used to tell stories about.
