[1] The character Júlio was originally derived from a Christmas special that aired in 1989 called "Banho de Aventura" (Adventure Bath) on the program Rá-Tim-Bum.

[6] According to Bia Rosenberg there were plans for the show to make use of animatronics for the chickens, but with reduced costs for normal puppets made created by Fernando Gomes.

[8] On July 9, 2012, another reformulation took place called TV Cocoricó, starting to present live episodes focusing on interviews with guests and sketches.

[10][11] The series revolves around the daily life of an eight-year-old boy named Júlio who lives with his grandparents on a farm known as Cocoricó located in a town in the interior of São Paulo known as Cocoricolândia.

In some episodes, Júlio and his friends are also tormented by Dito and Feito, a pair of troublemaking animals who love to make pranks with the farm residents.

During its premiere in 1996, Cocoricó was accused of plagiarism by cartoonist Ely Barbosa who alleged that TV Cultura copied one of his projects for a children's show entitled "Celeiro Encantado" which was originally created in 1990 for Rede Manchete, but was never produced.

[21] After the debut of the new version in 2003, the series became more popular and known among the public, according to Fernando Gomes in an interview, the program managed not only to attract attention from children, but also from adult audiences, in addition to being considered one of the best puppet shows in the world, being recognized at international festivals.
