The Windmill Vandals are a group of 4 Horsebacked Vandals (Eastern Germanic Tribesmen) who once plagued the land of Nowhere. 250 years prior to the TV show's events, the very first owner of the farm, Jiles Galette built the windmill at a time everyone else depended on waterwheels built by these 4 vandals. One day, the water dried up and it made Galette the only man with a working mill, the vandals were not happy. They tried to go to his farm and kill him, but fortunately Galette managed to stop them by carving 4 magical symbols on his windmill fins. Legend has it, if the windmill stops turning, the vandals will return from the dead and get revenge on all who possess it. In the episode in which they appear, the windmill breaks, and the Vandals appear as wraiths to come and destroy the farmhouse. The mill is broken and repaired several times, until finally it is fully fixed, and the Vandals banished forever more.
The Vandals appear whenever the blades cease turning, and disappear instantly upon them becoming mobile again.
- It should be noted that when the vandals cut Eustace's head off, the next time they disappear Eustace's head may have gone with them
- In the picture when the vandals were alive and attacking the farmhouse,it should be noted that the vandals used diferent weopons from what they have now during the attack on the bagge family
- In some episodes, the Windmill gets destroyed by monsters and the Windmill Vandals don't appear.
