Jo, Zette and Jocko

The Adventures of Jo, Zette and Jocko is a comic book (or bande dessinée) series created by Hergé, the Belgian writer-artist who was 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 monkey Jocko.
Jo, Zette and Jocko appear on the rear covers of some editions of The Adventures of Tintin series but never appear in the stories, while there are a few cheeky allusions to the cosmos of the Tintin adventures within the Jo, Zette and Jocko albums.
