Due to this, Yaya is often annoyed by him, and fines him more than the other students at school, even when he is just making fun of her. Gopal is possibly the most feared one of her biscuits, that he ran with an incredible speed when hearing of them (Season 1, Episode 2). Still, they get along well with each other from time to time, and also make a great team during combat. Sometimes when Gopal insults Yaya's Bicuits, Yaya gets angry on him. But they're still very good friends.
