One of the rabbits mention getting confused that one of the rabbits wore a brown shirt that matched his fur, and that they got confused which were his buttons or "nipples". Played for laughs.

Male main character is fighting with Peter Rabbit, Peter pulls the mans pants down and we see his boxer shorts.

A CGI animated character runs by yelling streaker (nothing shown, just an animated animal)

A male and female main character do one kiss

Peter attempts to shove a carrot into the old Mr McGregor's behind.

A cockerel makes a reference to having 'fertilised all those eggs'.

An older man dies on camera following a heart attack. He is seen falling to the floor with his eyes open. It's clear that he has died when he's poked in the eye as another character confirms.

The farmer and rabbits fight each other with escalating violence. They put animal traps in his bed. They electrocute a door, so he is violently throw across the room. He throws dynamite at them like grenades. They feed him blackberries because they know he is allergic, so he has to use an EpiPen to avoid anaphylactic shock. A rabbit uses dynamite to explode the roots of a tree, which wrecks a home.

When it starts to rain one character says "Damn it", but it is hardly hearable due to the rain sound, plus it's a British film and that's not really a word of profanity to them. One use of the slang word HECK.

Damn is used in a song

One reference to flatulence. This is for humourous purposes when a character attempts to lipread.

The older McGregor is brifely seen drinking beer in a flashback.

The younger McGregor injects himself once. It's presumably an antihistamine or something similar as he does it after having an allergic reaction.

A man is intentionally targeted with his allergen and is seen going into anaphylactic shock. He self-medicates with epinephrine immediately and survives. He is not shown to have any other ill effects after the epinephrine treatment. Viewers should note that in reality people going into anaphylactic shock should be rushed to the nearest hospital immediately following epinephrine treatment.
