Willy The Worm - Water Sensor

This larger version of our bestselling Willy the Terracotta worm is on a mission to ensure that plants and flowers the world over remain well-watered. His friendly face pokes out of the soil next to plants and vegetables and when well-watered he turns a darker shade.
As Willy and the soil start to dry out he changes to a lighter colour, letting gardeners know that it's time to fetch the watering can. There are 16 16cm terracotta worms in each appealing display.
