Dutchman

This is your rooster, or rather your parents' rooster. They sent him to you so that you could cure him. There are many clinics in the city. His name is Dutchman. The most important thing is that when he is alone, he turns into a human. So, you left the rooster alone in the apartment, but forgot your phone in the apartment. You went into the apartment and saw a guy. He saw you and stood there and said, "Dutchman, I was caught."
