When Lucy wins tickets to see Blink 182 in a competition, Josh is desperate to take them off her hands – after all, he's a huge fan of the band, and Lucy's such a geek she's never even heard of Blink 182. Lucy agrees to give the tickets to Josh, but on one condition: Josh has to perform a truly unselfish deed in order to qualify for the tickets. Of course it's a terrible struggle for the scam-meister, but Josh learns a whole lot about himself in the process. Elsewhere Mel is upset (though refuses to show it) when Trent appears to be going on a date with another girl. The confusion is resolved later in the episode when it turns out that Kelly is Trent's cousin, not his date and he and Mel become friends again.

Mel asks Scott Taylor to the school Christmas disco, causing Trent to get jealous. Lucy is cast as Mary in the Nativity play, a part Wendy wants. Josh fills Brian and Sophie in about Christmas. Lucy gives Wendy the part of Mary in the play, but Wendy becomes extremely demanding. Mel gets cold feet and won't go to the disco, so Brian morphs into her and goes in her place. Mel finds out and rushes to the disco, only to find Brian-Mel kissing Scott, right in front of a heart-broken Trent! Mel attempts to repair the damage caused by Brian, only to find out some things about herself. The school Nativity play becomes a strain on Lucy and Wendy's friendship. Josh has nightmares and is visited by ghosts in a plotline similar to that of Dickens A Christmas Carol.

Mel gets a job offer as an assistant to a fashion photographer. However, her audition takes place during school, so she goes to the audition whilst Sophie (who is not a very gifted morpher) morphs into Mel and goes to school. Unfortunately, she goes around kissing everyone, including Trent, Frankie and Mrs. Hardman. She is referred to a child psychologist. Sophie panics when seeing the psychologist and Mel arrives to take over. She soon transforms to a lady with Red hair to make sure the psychologist doesn't see there are two Mel's. However, Sophie cannot morph back to her original human form, and decides to keep another look, thus introducing a new looking Sophie (Carla Medonça).

Brian and Sophie become hooked on a trading card game, and will go to any lengths to obtain more cards. They end up stealing and selling the school laptop. They then discover there is a rare card (Madonna) that they need to find. They find the card, but realise they have wasted their time and money. They feel very silly.

It's Valentine's Day, and Josh is trying to get a date with Tanya Thomas, but makes the foolish mistake of taking Brian's advice on matters of the heart. Mel is the object of desire of Andy the Freak and Frankie when all she wants is a 'joke' Valentine's card from Trent. Sophie follows her heart and writes a card to her true love: the dishwasher. Sophie asks the family what Valentine's Day is, but in an episode a few years ago when Barbara Durkin played Sophie she is trying to act calm in front of a teacher who has come to visit the house and she says "This happened to me once on Val.... Valentine's Day".

When Lucy wants Brian's help with her magic act, his ambitions go far beyond being her assistant. Mel runs in the school's sponsored FunRun with Andy the freak in a pantomime horse costume.

Brian has a new pet: Fluffy the goldfish, but when she's fed on a diet of fried egg, bacon and beans, the unfortunate Fluffy soon floats off to the big fish tank in the sky, leaving Brian devastated. He then holds a funeral for his beloved Fluffy, which goes well. Josh attempts a challenge at the diner: eating 50 courses. He asks Brian to morph into him, and eat 48 of the courses. The first course is fish fingers, devastating Brian. He quits, leaving Josh to eat all the food. Mel later takes out insurance with dozens of spare goldfish, which she stores in the bathroom, and Brian thinks that the new fish is Fluffy back from the dead.

Brian is desperate to join Lucy at the Brownies, but she refuses for obvious reasons. Undeterred, Brian forms his own association – The Brianies – with its own code of conduct. Meanwhile, Mel has got a job at the diner with Sophie later joining her to help her out...with some disastrous results.

Mel notices a hunky boy who seems to attract all the girls. He seems to know her too – but there's a shock in store for her when she discovers who he really is. She persuades Sophie to morph into a girl from school (played by Lucinda Rhodes-Flaherty of KateModern fame) and gets her to find out more about him. It turns out to be Andy The Freak. After Frankie and Pete refuse to hang out with Josh, he investigates and find out that they attend a stamp collecting club. He then hesitates to be seen with them, fearing people will think he too is a stamp collector. Mel bans Brian from playing with CJ, fearing he will 'break' him as he does with everything else. However, whilst playing pirates, Brian breaks CJ's leg after knocking him off the top of the sofa with a plank. Continuing to play pirates, Brian then goes onto bury all his 'treasure' including the TV, fridge, Microwave, and CJ.

Josh's latest scheme ends in detention after he sells a computer password to Frankie, while Brian watches a series of sci-fi films and discovers the general public believe aliens to be bad guys – so he sets about changing people's opinions.

The children are outraged to discover Sophie has put them up for sale on the Internet – and what's even more mortifying is the price she's asking. The family also get involved in the school charity fair, where Mrs Hardman ends up dancing with three different Joshes.
