The Plutos were based in French Lick, Indiana at the French Lick Springs Hotel and frequented the West Baden Springs Hotel in nearby West Baden Springs, Indiana.
Their name derived from a bottled water produced at the Hotel. The Hotel bordered on a local salt lick and mineral spring and the minerals from the spring made the water act as an effective and marketable natural laxative. The product was branded as "Pluto Water" with an image of a red devil on the label. Their frequent rivals, the West Baden Sprudels, came from a hotel on the same spring that had also bottled the water and sold it as "Sprudel Water".
