Mort is asked if there was a lot of inbreeding in his family. He replies that he might be his own grandfather.

Minor crude jokes throughout the series, nothing too serious.

Some comic violence throughout the series

The character Mort survives many violent accidents. All of which comedic and non-graphic. Almost all of which involve explosions and most of such accidents happen in the 3rd and 5th seasons

Karl is a villain that appears throughout the series as a recurring character (meaning that he is neither a main character nor a minor character). In nearly all of his appearances, he threatens to kill King Julien and/or King Julien's friends. He never succeeds though. Almost none of his attacks involve injuring King Julien severely

King Julien's bodyguard Clover can regularly be seen punching or threatening to punch people. This is for comedic effect

A few action scenes, mostly resulting in comic relief.
