There is no sex shown in this movie! However, there are a lot of references about it in this film. There is one scene where Mario suggests that he is going to dominate Princess Peach which we all know is something sexual.

There is a lot of fighting, shooting, and stabbing in this film. There is one scene where Luigi tries to shoot Giga Bowser but doesn't succeed because Giga Bowser is too powerful. There is another scene, after Mario and Luigi turn Bowser back to his old self, where Luigi continually jabs Bowser with a pocket knife and threatens to shoot him.

The characters don't use any horrible curse words. They may say "What the Hell?" or "Damn" maybe even "Bastard" but nothing truly bad

There are no uses of drugs or alcohol, but there are mentions of it.

Please note that all of the characters are plush toys visibly being controlled by two guys' hands so the violence is not at all realistic
