La que se avecina

Luis Miguel Seguí (Leo) and Antonia San Juan (Estela) were a couple in real life.

According to co-creator Laura Caballero, the opening credits weren't use since season 3 because it was expensive to create new cartoons every year (many actors left and arrived the series on season 1, 2 and 3) so they just displayed the cast names.

According to co-creator Alberto Caballero, Eduardo Gómez asked to be written out because he wanted to rest.
