Here's a great little freebie for any fans of the Gruffalo (or, perhaps more accurately, those of you with little fans of the Gruffalo.) It's all to support the joint venture with Yorkshire Tea and the Woodland Trust to plant more trees up and down the country. As for the the app itself, it contains several educational mini-games that focus on planting trees, with user reviews being rather positive. Oh, and for those of you worried it will eventually cost you an arm and a leg need not worry, as there are no in-app purchases with this one. Thanks to NASHJ @ HUKD!
