Rapsgaliwn is a rapper, who claims to be 'the best rapper in the world'. Recognised for wearing gold. He is Dona Direidi's cousin. Each episode revolves around children asking him a question and he produces a rap with the answer after doing a bit of research.
Despite being a Welsh language programme for Welsh speaking children, English subtitles are usually available with the phrases reworded in order to maintain a rhyming pattern after translation.
