Similar but I think these are different and better. The Blue Sunshine has a faint blue ring on the oral disc with some orangish color in the skirt. These are a much more vibrant color throughout, with a nice purple at the base of the skirt and more whiteish silver skirts. I think these are something new and different. But thats just my opinion. I would come up with something sweet and submit it to thecoralvault.com and see what Mike B. says!!
