I think (at this point) they are unique to Jolly Holiday. From what I remember, the chocolate one was is the "standard" flavor and the rose/raspberry one was supposed to be the "seasonal" flavor. However, they've had the rose/raspberry one from nearly the beginning, so I don't know if it's also become a standard (I think it has). I think they tried a passion fruit one a while ago, so perhaps they are doing an occasional seasonal flavor, along with the two "standard" flavors.
