The theme is the amazing Halloween Day! Dongyup is Shin-cream. Boom is Boom-ky. Seeing Hyeri, Dongyup asks, "You use Halloween to dress up prettily huh?" Hyeri is the ghost bride. Hanhae is the astronaut and comments awkwardly, "Ah, it's hard to breathe on Earth."  From Street Fighter, Donghyun Ken shouts out, "Hadouken".
