Ten years old, Arnold Tibbs, lives with his mother, father, brother Baz and sister Fiona. Arnold has an imagination, a very vivid imagination, which seems to cause a lot of trouble, in other words, he is a rascal. He does not mean to cause trouble, he just lets his imagination take over, which is a problem whether he is at the shops, in the museum, on a school trip, at the zoo, at home, or just mooching around.
