My Parents Are Aliens

When Mel skips school to visit her mother's grave (she won't explain why at first) her teacher Mr Coleman decides it's time to pay a home a visit. Meanwhile, Brian has developed an allergy that causes him to sneeze and morph uncontrollably. Mel starts training Sophie to behave like a 'real' mother, while Lucy attempts to diagnose Brian's allergy. Unfortunately, during his visit Mr Coleman sees Brian sprout a new nose and ears, and resolves to return with their social worker. Josh is determined to hold a party to improve his social standing – could this somehow save the whole family from being taken back into care? Will the world find out Brian and Sophie are aliens?

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 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).

To celebrate their "phone-iversary" Josh convinces Sophie and Brian to buy him a new mobile phone. Sophie also gives a mobile phone to Brian, however the phone wipes his mind of all his alien memories. Meanwhile, Josh believes his mathematics teacher has fallen for him. Josh, Lucy and Wendy all discover love through texting.

Brian and Sophie learn about age concerns which leads them to either wanting to move in a retirement home or get wrinkles! Meanwhile, Josh's voice breaks and uses it to pretend he's Brian phoning school to say that Josh is ill.

Brian turns himself into a super hero. Josh won't act as his sidekick so Brian brings home eight-year-old CJ. Soon, the new boy is Brian's biggest fan – but alarm bells start to ring when CJ reveals he wants to stay on as part of the family.

Josh, Pete and Frankie are in competition for the attention of a new girl in school, but there's a surprise in store for one of them when they discover who she is. Mel has left for Canada and Brian is suffering in her absence, so takes matters into his own hands by getting a 'new Mel' from the children's home, while Lucy is enjoying having a room to herself, which soon changes as CJ starts launching desperate attempts to move in, even resorting to 'becoming' a girl!

Brian and Sophie crash-land by the sea and find four more children to foster – however their memories of the past seven years are wiped by Guido, the new avatar for the Galactic Guidebook, and are now unsure of how the new members of the family will react to the news of their alien identity.
