Sea Oats are a type of oat found in Xanth that is commonly used for food.
Grown in fields, sea oats give off a "pleasant swish and gurgle" sound emulating the sound of ocean tides. They are commonly harvested for their use in cooking broths. When cooked, a sea oat broth is not only salty, but also foamy. Cooks also had to be careful to only fill a bowl halfway with broth. If filled completely, the waves of the broth would spill over the edge of the bowl.
Sea oats are a cousin to the more hyperactive Wild Oats.
