Western Animation: Horrid Henry

"It's not fair when Mum and Dad nag-nag
"Stand up straight! Don't be rude!"
It's so not fair, cos the Killer Boy Rat stars
School stinks — kids rule!
So when they send you to your room,
Sing a little tune... You sing:
"Nah nah nee nah nah!" "
One of the theme songs of the series.

Horrid Henry is a British animated television series based on the book series by Francesca Simon produced by Novel Entertainment and Nelvana Limited (series 1 only), broadcast from late 2006 on CITV in the UK. The show has 4 series so far and has at least 190 episodes so far, making one of the most popular CITV shows.

This TV show is about a child named Horrid Henry who is, well, horrid of course. He also has a brother named Perfect Peter, who is just the opposite of Henry.

This show is an example of:

  • Abusive Parents: Horrid Henry's Mother and Father are kind of like this, but they are much milder than other examples of this trope. They dote on Peter all the time and excuse him for everything.
  • Accidental Misnaming: Henry is referred as 'Henrietta' by his great aunt Greta.
  • Added Alliterative Appeal: At least one character has a nickname like 'Sour Susan', 'Brainy Brian', etc.
  • Afraid of Needles: When Henry has an injection.
  • Annoying Younger Sibling: Perfect Peter.

  • Art Evolution: The animation seems to improve in series 3.
  • Beware the Nice Ones: Don't ever take Peter's Bunny and tease him with it.
  • Big Eater: Greedy Graham is like this.
  • Big NO!: Henry at the start, or end of every episode if something goes wrong. It would show him shouting "No!" and then it would zoom into his mouth, and then the title card appears.
    • Besides Henry, Peter and some of the characters did this as well.
  • Birthday Episode: Two of them; one for Henry, another for Peter.
    • Henry's cousin Steve had a birthday party too.
  • Breaking the Fourth Wall: Henry usually addresses the viewers. In one episode, Henry asked the viewers he needed help with the picnic that his father made, he then replied with "What do you mean ''no?'".
    • Peter did this too in some episodes about him.
    • Margaret did this once.
  • Brick Joke: In Horrid Henry's Sick Day, he was told to leave the taps on in the bathroom. At the end of the episode, the father opened the door for the bathroom, and then the house got flooded.
  • Catchphrase:
    • "Don't be horrid, Henry!"
    • "I dunno."
    • "It's not fair!"
  • Cats Are Mean: Henry's cat Fluffy in some episodes.
  • Character Name and the Noun Phrase: Most of the titles are like this.
