The Scareships were designed to take the place of the twins in the lookout tower so they could sneak away and goof off instead of stay on watch at the tower. They were later used by Tuff and Astrid to make it look like the Edge was well guarded in "Edge of Disaster, Part 2".
They were part of the twins' estate sale during "Living on the Edge". Tuffnut said they were made from their actual hair, and wasn't sure why none of the other Riders wanted to buy them. A merchant eventually bought them both, leaving Ruffnut grinning over the money she just made.
- The scareships are a clear parody to "scarecrows", except they're meant to scare off enemy ships instead of birds.
- Ruffnut Thorston affectionately names the scareships "Stuffnut" and "Fluffnut".
- Similar types of dummies were used as decoys for confusing the Snow Wraith.
