Add Full Plot
The melodious goings on at the Swann family residence continue this week with maths tests, signature perfumes and talking dolls on the song sheet, in CBBCs musical comedy series.
Isaac is in trouble and faces being booted out of the band after getting an appalling score in his maths test, while his brother and sisters attempt to rally round and help.
Aretha, meanwhile, creates a distinct pong when trying to concoct her signature perfume and Hadleys euphoria at having his own talking doll soon turns to disappointment when he hears what his namesake toy has to say for itself.
Elsewhere, Grandad arrives to finish his new album but lacks inspiration. When Issac tries to help his rocking grandfather rekindle his creative flair, he discovers an unusual way of solving his mathematical problems.
Isaac is played by Matt Morgan, Aretha by Dominique Moore, Hadley by Angus Harrison and Grandad by Alan Ford.
