 The comic being published remained until 1984, years before the TV series is no longer in production.
The Sítio do Picapau Amarelo (literally translated and roughly known as the Yellow Woodpecker Farm or the Yellow Woodpecker Ranch) is the primary setting for the series of children novels of same name, written by Brazilian author Monteiro Lobato.
 The place is described as "a small farm with a pretty cottage, surrounded by trees" and simultaneously close to several other subsettings: a stream, a virgin forest and a small village, both named the Tucanos.
The Chronicles of Narnia is a series of seven fantasy novels by C. S. Lewis.

O Saci is a 1951 Brazilian children-family fantasy film, directed by Rodolfo Nanni, written by Nanni with a story by Arthur Neves, and based on the novel of same name written by Monteiro Lobato.
 Noted for being the first family film to be ever made in Brazil, it is also the first theatrical "Sítio do Picapau Amarelo" adaptation.
 Introducing young actress Olga Maria as Emília and Paulo Matozinho as the title character Saci, it adapts the novel in which Pedrinho (Lívio Nanni) demonstrates interest in capturing the supernatural, one-legged mulatto boy figure, the Saci, inhabiting the nearby virgin forest.
 Curiously, in 1954 the film won the Saci Award, that rewarded the best films of the decade.
José Bento Renato Monteiro Lobato (April 18, 1882 – July 4, 1948) was one of Brazil's most influential writers, mostly for his children's books set in the fictional Sítio do Picapau Amarelo (Yellow Woodpecker Farm) but he had been previously a prolific writer of fiction, a translator and an art critic.
 He also founded one of Brazil's first publishing houses (Companhia Editora Nacional) and was a supporter of nationalism.
William Thompson Kirkpatrick (10 January 1848 - 22 March 1921) was an Irish teacher and grammar school headmaster.
 He is best known for having been the tutor of the two Lewis brothers from Belfast, Warnie Lewis and C.S. Lewis.
 C.S. Lewis, who would later become well known as a literary critic, novelist, and Christian apologist, lived as a resident pupil with Kirkpatrick from 1914-1917.
 In his autobiography, Lewis reports that he was significantly influenced by his tutor.
Sítio do Picapau Amarelo (literally translated and roughly known as "the Yellow Woodpecker Farm" or "the Yellow Woodpecker Ranch") is the title given to a series of 23 fantasy novels written by Brazilian author Monteiro Lobato between 1920 and 1940.
 The series is considered representative of Brazilian children's literature and as the Brazilian equivalent to children's classics such as C. S. Lewis, "The Chronicles of Narnia" and L. Frank Baum's "The Wonderful Wizard of Oz" series.
 Lobato's single original adult fiction, a sci-fi novel entitled "O Presidente Negro" ("The Black President") set in the far future, would not achieve the same popularity of "Sítio".
 The concept was introduced in Monteiro Lobato's 1920 novel "A Menina do Narizinho Arrebitado", and was later republished as the first chapter of "Reinações de Narizinho", which is the first novel of the actual "Sítio" series.
 The main setting is Sítio do Picapau Amarelo, where a boy, a girl and their living and thinking toys enjoy exploring adventures in fantasy, discovery and learning.
 On several occasions, they leave the ranch to explore other worlds such as Neverland, the mythological Ancient Greece, an underwater world known as the Clear Waters Kingdom, and outer space.
 "Sítio" is often symbolized by the character of Emília, Lobato's most famous creation alongside Jeca Tatu.

Emília, also known as the Marchioness of Rabicó or Emília, A Boneca Gente ("The Human Doll") is a fictional character and a titular of the "Sítio do Picapau Amarelo" series of fantasy novels written by Brazilian author Monteiro Lobato.
 A doll with a rough, antagonistic personality and an independent, anarchist behaviour, Emília is Lobato's most popular creation alongside Jeca Tatu and, according to studies and analyses of his work, she is his personification in the stories and that, towards the character, Lobato expresses his own ideas.
 Even though, Lobato has stated that Emília is "sometimes so independent that neither I, nor her father, succeed in controlling her".
