Sps needs a name

[CoralBeauties]

I got this coral from Bin as 3 tiny numbs and he called it a purple nana.  After it has started growing and encrusting its not a nana.  Anyone have an idea what it might be?  If not I need a good catchy name for it.  sorry about the cell phone pic but it is purple with green on the underside but the most striking part of it is has bright blue polyps.  I thought about something like papa smurf berry?
thanks
