Strange Happenings at No.4

During our holiday on Granny Wig's farm, me and Lizzy find a nest fill of brightly coloured eggs. We hide it in my guitar and sneak it home.
Back at No.4, we put the nest in the wardrobe, and soon forget about it. Strange things start to happen around the house; our carpet starts to grow, Mum's words get jumbled and Dad sprouts some hair....
Remembering the eggs, we find that they have hatched!
