The authors of the original idea are the TVE screenwriters Carmina Roig and Daniel Cerdà.
Both conceived it, first under the supervision of the director of TVE Catalonia, Paco Freixinet, and later under the former head of news programmes, Valentín Villagrasa.
Currently, the show is composed of the following blocks: Lunnis and their friends, The Musical Rocket, Lunnipedia, and UNICEF.
There they have to resolve all type of plots and problems, some caused by the pirate Lucanero, who wants to steal the Big Magic Book of the witch Lubina.
Beside the characters, the space was presented by the singer Lucrecia, between his première and 2008, accompanied, during the first season by Àlex Casademunt.
