Well the thing about this hedgehog is that it can be turned into a ball, just as it does in the wild in self-defence. It?s brilliant actually! Super soft, beautifully made in highest quality fabrics, the ?prickles? fabric being a work of art in itself. Every primary school should have one, but this will appeal to grown-ups too; it?s a very classy item in every sense! 8 inches 20cm.
