All of the characters are spoiled little children:

• Boisterous Billy – He is a hyperactive little boy, who is always filled with energy, and is very easily excited. He is always wanting to have fun, even when it's not the right time and place to do it.
• Bossy Bethany – She is a bossy, yet very independent, strong-witted, little red-haired girl, always telling others what to do. Bethany is always bossing other people around, by telling them what they are doing wrong and telling them to do it right, or by telling them what to do. Sometimes, her bossiness can get the better of her.
• Curious Calvin – He is a little Black English boy, who is always willing to know anything and everything. He is always asking himself questions about everything, why they are the case.
• Clumsy Clarissa – She is a clumsy, yet well-meaning, little girl, but she cannot help but have all kinds of accidents, whether she falls over, or knocks things over, often causing them to break.
• Contrary Constance – She is a posh, quick-witted, contrary little girl. Constance dislikes being told what to do. She will either flat-out refuse to do as she is told, or she'll do the exact opposite of what she is told to do. Like, whenever she's told to read quietly, she is read out loud, and when she's told to do her homework, she refuses to do it.

• Grown-Up Gabby – She is a big girl in curls she is really an adult. Gabby is willing to act as grown-up as possible, like putting on makeup (as shown in her book), wearing her mum's attire (like her mum's hat, dress and high heels), and even disapproving of things she claims are childish.
• Helpful Henry – He is a good little boy. Henry is always eager to help other people, even if they do not need help. Henry is always eager to help other people, even if they do not need help. Sometimes, Henry's "helping" can lead to trouble.

• Pickin' Peter – He is a little boy with a filthy habit of picking his nose, much to his mum's dismay. He always does his best to pick his nose whenever his mum is not looking, so to avoid certain punishments for doing so. As shown in his title card, he also has a bad habit of picking his ears.

He always acts silly, talks silly, and even dresses silly, usually wearing his underpants on his head, and flippers instead of shoes. He always does meaningless things, and even says meaningless things, like saying, "Happy Christmas!" when it is not Christmas, and even talking topsy-turvy. However, despite being very odd and wacky, he is not mean – he is really nice, and even brave, when the need arises.
• Sulky Sue – She is a little girl with a problem with being miserable and unhappy most of the time, hence her nickname. Sue is always acting miserable. Even the funniest, most exciting, and most entertaining things cannot cheer her up, and she often mumbles that she hates the thing she's about to do, even going as far as calling them "Stupid". Her parents are the exact opposite.
• Tantrum Tabitha – She is a naughty, little blonde girl who always throws a tantrum. Tabitha has a terrible habit of causing a scene.

• TV Trevor – He is a little boy who has a habit of pretending to be the main character of every show he sees on television. Trevor always finds himself watching television, and when he is done with the show, he pretends to be the main character. When it comes to watching imported shows, he will put on a US accent. Trevor does not like when his parents threaten to take away the television.
• Wide-Awake Wesley – He is a Black English boy who is not going to sleep. Wesley has a bad habit of staying awake all night, and will do anything to avoid going to sleep, even when it is time for him to do so.
