The Adventures of Jo, Zette and Jocko
The Adventures of Jo, Zette and Jocko is a Franco-Belgian comics series created by Herge, the writer-artist best known for The Adventures of Tintin. The heroes of the series are two young children, brother and sister Jo and Zette Legrand, and their pet chimpanzee Jocko. Jo, Zette and Jocko appear on the rear covers of some The Adventures of Tintin comic books, but never appear in the stories. A few Jo, Zette and Jocko comics allude to characters or events in The Adventures of Tintin.
