The River Gang girls have got it in for Rosie. They used to be her friends, but now they think she's weird and call her names like "Pimple-head".

They make fun of her dog Dog too. Worst of all, they've turned the new girl, Curly, against her.

If only Rosie could be like the heroine of her games, the amazing Queen Roo-Pan.

Then she'd show them. But is she brave enough to risk being laughed at and make a stand?
