Penelope MUST come up with a way to defeat the jealous green-eyed monster, without having an outburst at her best friend, or her mum. Luckily, Penelope has a few tricks up her sleeve!

Penelope Kingston wants to be perfect. And most of the time she is good, sensible and calm. But then sometimes Penelope is bossy, angry and frustrated.
