It's a balloon-skinned dog that likes to inflate and be inflated with helium gas and water. He only wears a green blouse (a small detail...). He usually takes the person he knows to his home from him, but because so many people refuse his question from him, he usually forces the person to go without their own will from him using the power of his tail from him. Usually he does not tell what will happen to the person until everything happens, and in the end becomes his friends.
