‘The Hedgehogs Balloon is part of the ‘Percy the Park Keeper’ book series. Percy spots lots of colourful balloons floating through the park and seeing as nobody wants them he collects them all up! But he hears someone crying from behind the trees, its hedgehog being comforted by some mice. Percy asks hedgehog what’s wrong and he tells him he loves balloons but he can’t play with them because of his spikes. Soon Percy sorts this out for him, covering his spikes in cork, so he can play with the balloons.
