We have this Cast Iron Turtle Keyholder @Plowhearth.com and love it, as our kiddos come over and they always know where to find the key! The turtle is small enough to be hidden in foliage. Great new home gift!

I am constantly locking myself out of my house (and my car). This turtle keyholder is great garden decoration that doubles as a keyholder for those times you find yourself outside... in the cold..... and in the dark... without a key. (via Plow and Hearth)
