El Mundo del Profesor Rossa ([Spanish Language] for The World of Professor Rossa) was a Chilean children's television show centering on a professor named "Professor Rossa", who taught about Chilean national animals, mountains and nature. The show was broadcast on UCV TV from 1981 to 1984 and on Canal 13 from 1984 to 2001.
The show was set in Professor Rossa's house. The first seasons, the program only starred the professor and piano composer Valentin Trujillo. Guru Guru appeared later, as a man in bird disguise who delivered the children's letters to the professor, the bird started to have a "father-son" relationship with the professor, so Guru Guru left the postman role. Don Carter came to fill the role and the show was expanded to four characters.
The four characters interacted inside the house always doing a mess, irritating the professor to bring humor to the program. In some seasons, the professor moved the show from his living room to an underground room connected by a secret passage, leaving the first set.
