Henry is secretly cloning an army of FluffiesIn Horrid Henry's Sleepover, two cats that are identical to Peter's cat, Fluffy, randomly turn up outside Nick's house. And in Horrid Henry's Petsitting Service, when Henry dreams of his petsitting service, he imagines himself showered with cash and holding the two Fluffies. <<|Wild Mass Guessing|>>
- It could just be two different cats.
Peter and Henry's behaviour is actually exactly the same.It's from the point of view of the parents, well.. the mum in particular. They're not ... well, to say the least. Peter is a Golden Child. Henry is the Scapegoat. The episode with the brainbox competition involved roles switching for a day and it never actually happened... it was just a imagine spot.

Henry was once a very good kid.Once upon a time, when he was a toddler and growing up further, Henry was a very sweet kid who respected his parents and was responsible and respectful. But then, his parents decided to have another child. In came Peter, and his parents started putting FAR more attention to Peter than they did to Henry. He was so sick of all the newfound attention Peter was getting, and his parents barely paying any attention to him, that he decided to become the horrid kid he is today.
Mom and Dad's bias towards Henry and Peter is all Henry's own fault.<<|Wild Mass Guessing|>>
