Hattifatteners are always on their way. They wander around in large flocks, waving their small hands. Hattifatteners often sail the seas in small boats, but also travel on the land. No one knows where they come from or where they go.
Hattifatteners are mainly completely harmless. They say nothing and do not hear, just tremble and continue their journey. However, during thunderstorms, they become electric and then you should be careful.
