Can someone here please tell me what on earth is this plant/growth/alien specimen that looks to me like a radioactive deformed pineapple is and what it's doing all over this small town in Ontario, Canada? It looks tropical and so out of place but I spotted it all over the place in the Kawartha Lakes/Lindsay area of Ontario on a recent road trip and am obsessed with knowing what it's deal is. It was both on land and in water, and looks menacing. Can I add more than one picture?
