Castelo Rá-Tim-Bum.

Nino is a 300-year-old boy who lives with his uncle, Dr. Victor, a sorcerer and scientist, and his great-aunt Morgana, a 6,000-year-old witch. The three of them live in a castle in the middle of the city of São Paulo. Apprentice sorcerer, Nino has never attended a school, because of the unusual age of 300 years. His parents left him living with Victor and Morgan, because they needed to travel on an expedition into outer space, taking their two younger brothers. In spite of having animal and supernatural friends in the Castle, Nino, feeling lack of friends like him, decides to do a spell he learned with his Uncle Victor, and ended up bringing to the Castle, three children who had just left school. Free of loneliness, Nino receives the visit of the three daily.
