Serena is a horrid girl who treats her little sister terribly, bullying her and telling lies to their mum in order to get the younger girl into trouble.
One Easter, the girls get given lots of chocolate eggs and Serena saves one of hers for weeks just so that she can eat it in front of Ellie and make her jealous.A few weeks later, Ellie breaks a flyswatter. Serena sees and threatens to tell their mum if Ellie doesn’t agree to be her slave, making her do all kinds of horrible chores.
Whilst eating her saved chocolate, Serena doesn’t notice the tiny egg laid by a fly in her sweet, and eats the whole lot up. Waking up the next morning, Serena feels strange, and doesn’t realise that she’s turned into a fly-girl. Ellie sees her and uses her flyswatter to flatten Serena, finally getting rid of her horrid sister.
