The mute character Troubadour, who served as Pompadour's clerk and assistant, disappears in later seasons and does not return.
French author Laurent de Brunhoff pronounces the name Babar as "BUH-bar", but the TV series pronounces the name as "BAB-bar".
Basil, Victor, Pompadour and Troubadour were characters who were invented specifically for the Babar TV series in 1989. After Mango Madness (1991), all bar Pompadour, who has a non-speaking appearance in The Departure (2000), cease to return, which may have been a budget issue during later production. In the CGI animated series Babar and the Adventures of Badou (2010), these characters also never resurface.
Babar's high-strung minister of protocol, Pompadour the elephant, was originally designed wearing a turquoise long coat with blue and white accents. He appeared this way in Babar: The Movie (1989) but in the original series, his attire was recolored to shades of pink and orange. In "The Departure" the first episode of the 6th Season, Pompadour wears a Powder blue variant of his attire.
Initially viewers who hadn't read the original Babar books but had watched the TV series assumed that Babar's oldest son, Pom, was named after Babar's minister of protocol, Pompadour. Actually, Pom's name origin is unknown (in French the name "Pom" is short for "Pomme", or in English, "Apple", and it used to be a fairly common boy's name), and he was originally written as a character (one of Babar's triplets) in the books, whereas Pompadour was designed specifically as a character in the TV series and earlier 1989 film adaptation and never appeared in the original books.
