They didn't had an official release because they were the first breed to be created for an Holiday and the idea of an Holiday release still didn't existed (neither Hollies -created after them- had a properly Holiday release, I recall that users in the forum told that the eggs just appeared in the cave without announcement, since it was kinda a joke). The common reception for them is as Halloween Dragon, since their creation is part of the Halloween event, so I would put them under "Holiday Dragons that have to be created".
