- "Fiercely territorial, Singetails don't just breathe fire--they send it blasting out of their jaws, gills and tails.
First discovered by Spitelout when he colonized Storehouse Island, the elusive Singetails prefer to scare away their enemies with long-range attacks, like hurling fireballs from their tails. However, Singetails also pose a danger in close-quarters combat by shunting jets of flame from their gills lining their exposed underbellies.
No dragon or rider can ever get the drop on a Singetail due to its articulated eyes -- they swivel to the sides and back of its head and give the Singetail a 360-degree lay of the land. Since it can look at two directions at once, the Singetail can act as its own tailgunner"
- "It's best not to get in a Singetail's way. These territorial Dragons can blast fire out of their jaws, gills, and tails!
Sneaking up on a Singetail is hard enough, but finding its weak spot during battle is nearly impossible!"
In "School of Dragons", Singetail eggs are normally oval shaped. They are orange with red spots in colour. In "Dragons: Rise of Berk they look more like a fire bush, with frill-like fins lining across its length and they are orange.
Hatchling to Adult
Singetails have a wide, flat body and a long tail. They have four wings, like a Thunderdrum, but with the bigger pair being set lower on its back. They have a spiky face with chameleon-like eyes that allow it to see in multiple directions, as well as several big, sharp spikes along their backs and tails.
It has eight extremities (four wings and four legs), two more than any other dragon and four more than any other species.
Titans are dark purple, with darker stripes on their wings and back. They also developed another row of spikes along their back.
The Singetail's eyes are able to move their eyes in two different directions at once. Their eyes also swivel to the back and sides of its head, giving it a 360-degree view, much like a chameleon. As such nothing can sneak up on the Singetail.
Singetails can shoot fire from not only their mouths, but from their tails and bellies as well. The fireballs that the Singetails produce are scarlet in color. Singetails can use its fireballs to mark their territories or as a signals to call for reinforcements from its own species.
The Singetail has proven to mostly count of its fire power against enemies in the air. As proven to be quite unpredictable opponent against Monstrous Nightmare, Deadly Nadder, Rumblehorn, and Night Fury. Though this is mostly for the first time opponents that never battle Snidgetail before. This dragon has proven to have no blind spot on its body as it can take on a Night Fury; as such, it is able to surprise dragons that have great accuracy like the Night Fury that might think the belly is a vulnerable spot.
Endurance and Stamina
This dragon is shown more in the air then on the ground, as its stamina must be really high to not to take a rest, as it was being chased by its enemies for long distances. Its high stamina is further proven from being chased and being able to take some of the attacks from the combined powers of the Rumblehorn, Monstrous Nightmare, Night Fury and Deadly Nadder.
Speed and Agility
This dragon is very fast and agile, able to dodge attacks from its foes.
This dragon has proven to be smart enough to try to take over islands; it will call others of its kind by spreading fire on trees to call reinforcements to defend their home. It can be said therefore that they are the smartest dragon seen thus far in the stoker class. Also it might be possible SnidgeTail can tell by their kind that it's for sign of reinforcements as their been many fires that have been seen near Berk.
Dragons: Race to the Edge
The Singetail was first discovered by Spitelout Jorgenson on Storehouse Island in Turn and Burn. When Stoick, Hiccup and Snotlout go to Storehouse island in search of Spitelout, Hiccup and Snotlout trigger a trap and get stuck in a net. When they ponder why Spitelout set up a dragon trap, they encounter a Singetail circling them. Spitelout arrives with Kingstail to rescue the group and leads the large beast away. Upon learning that Spitelout was making a storage house there, Stoick argues the beast itself makes the island too dangerous of a place to have the storage house. Hiccup tries to calm both sides down to reach a mutual decision, but it proves difficult with the Singetail's presence and the Jorgensens' point of views.
After determining the belly to be the weakness, they argue over who gets to take the shot before taking off. Spitelout shows them some places the Singetail has burned, and Hiccup knows something's wrong as the fires aren't concentrated. When they try to enact Hiccup's plan, they find out that the dragon's underbelly also emits fire. They soon figure out that the fire the first Singetail was making was calling for back-up. More Singetails arrive, and the team agrees to leave.
