The ending credits of the French language version has Shag-Shag coming out of a dark portal, followed by some conceptual art of every character(s) by Nina Wolmark. In various international prints, it just shows some footage of the six main characters from various episodes. Also the show's theme song plays during the credits.
In the final episode, the concept art is replaced by images of the main characters and the "Flashbic" song plays during the credits rather than the theme song.
