What do you think the story is here? Impossible-to-resist price cuts at the Discount Landscaping Depot? Commemorative animal statuary for deceased family pets?
Did they start with the fountain, then, labelled as statuary lovers, fall prey to tragically misguided gift giving?
Or, my favourite possible explanation: a donkey, a rabbit, a chicken and a lion were hanging out at the local watering hole, when suddenly, a magical mermaid appeared, turning them all into stone. Or at least white-washed cast concrete.
