Introduction

Yoyo is just an average schoolgirl…until she wears her super-powered T-shirt. Then she becomes the smartest, fastest, coolest kid in school! But even the best clothes get too small in the end when you are a growing kid, and eventually Mum decides the T-shirt has to go… in the bin! But is that the only solution?

Meet Yoyo and Her Family

Yoyo

Yoyo is the smallest kid in her year at school. But she has a secret weapon: she owns the world’s coolest T-shirt!

Kevin

Kevin is Yoyo’s little brother. He loves his big sister, his Tae Kwon Do classes and the planet! He also has a secret passion for Yoyo’s T-shirt…

Mum

Mum’s an accountant by day.. She’s busy, hard-working and loves her kids. She also loves a tidy apartment!

Dad

Dad is a bit of an inventor in his time off work. He likes making things out of scraps and invariably makes a mess which Mum has to clean up…again!

Grandpa

Grandpa lives with the family. He loves keeping fit, playing mahjong, and hanging out with his friends in the evening. He likes to quote that famous ancient Chinese philosopher Confucius.

Frosty

Frosty is the family’s dog. He loves them all equally but especially loves Mum when she’s cooking char siu bao.

Join Yoyo, her planet-loving little brother Kevin, and her friends in this exciting, fun quest to save the magic T-shirt… and learn from her amazing family about what you can do with your old clothes to help save the planet!
