Dooly the Little Dinosaur
Gil Dong's niece. His parents went to study abroad, so Gil Dong and his wife is taking care of him in their home. He cannot speak well yet and is wearing a diaper. He is very stubborn and used to fiercely fight with Dooly at first, but as time goes by he likes Dooly very much. He is one of the important reason that Dooly can live in Gil Dong's house even though Gil Dong hates him so bad.
