Felix's school is haunted again, only this time it's not the spirit of the school founder and the nuisance he caused last time, but the long dead school principle. A coincidence causes the former school principle to rise from the grave. When she manages to return to real life she uses magic to shrink Felix's teacher and his parents, and take over the school. It's up to Felix, Ella and the gang to save the school and bring everyone back to their original size. Packed with fast-paced excitement and lots of humour 'Help, I Shrunk My Parents' is fun for the whole family.
