The Silver Olympus Dragon was introduced along with the Bronze Olympus Dragon, Gold Olympus Dragon, Olympus Habitat, and Olympus Flag without notice on July 27th, 2012.
- On August 8th, 2012, it was confirmed by Backflip Studios in this Facebook post that the Silver Olympus Dragon is not a limited dragon.
The Silver Olympus Dragon can only breed with a Cyclops Dragon, a Bronze Olympus Dragon, a Gold Olympus Dragon, or with another Silver Olympus Dragon.
Breeding two Olympus dragons together can only result in one of the two parent dragons. For example, breeding a Silver Olympus Dragon and a Gold Olympus Dragon will NOT result in a Bronze Olympus Dragon.
The 35-hour breeding/incubation time is most likely related to the fact that there are 35 sports in the Olympic Games (28 Summer sports and 7 Winter sports, although 2 sports were removed from the Summer Games and have not been replaced).
The five dots on the Silver Olympus Dragon's tail could be a reference to the five rings used in the Olympic symbol while the flame on the end of the tail could be meant to symbolize the Olympic Torch.
Most of the automated names specific to the Silver Olympus Dragon, as well as to the other Olympus element dragons, are from Greek or Roman mythology.
