River Adventure (A Keltie Wood story)

Polly, Pepper and Fred are three young hedgehogs that live in Keltie Wood, home to a community of animals. It was meant to be a perfect picnic on the first nice day of the summer holidays, but Polly and her younger brother and sister had reckoned without the interference of naughty Walter Weasel. What was meant to be a relaxing day out turns into quite an adventure, especially for poor Fred.
