- Shrouded in a dense haze, Breakneck Bog has earned a reputation for being a haunted graveyard for scuttled ships and lost sailors. In actuality, the Bog is home to the scrap snacking, smoke-spewing dragons known as Smothering Smokebreaths.
Breakneck Bog is an island in a island group in the shape of a man's hand. Breakneck Bog is the thumb.
According Ruff and Tuff, Breakneck Bog was home to a fog monster. However, Astrid's grandfather believed it was pirates. Trader Johann inadvertently took his ship too close to Breakneck Bog. It was taken by the fog monster. The Riders arrived, rescued Johann, and went to the island. There, they discovered that the fog monster was really a pack of Smothering Smokebreaths. They were able to retrieve the chest from them and left the island.
The Berserkers then took a Smothering Smokebreath nest from the island and gave to Johann as way to weaken Berk's defense. However, the plan failed and Johann took the adolescent Smokebreaths back to the island.
Dragons: Race to the Edge
- The remains of Thor Rock was shaped the same as Breakneck Bog.
- In Rise of Berk, the Smothering Smokebreath is not found on Breakneck Bog, but the Grapple Grounder, Tide Glider, and Sand Wraith are.
- Breakneck Bog is similar to the legendary Bermuda Triangle since most ships and sailors get lost and never come back.
