Potato, Sand

A potato that grows best in sand and harly needs water, as opposed to other potatoes that definitely need water, and nutrients from the soil, and actual soil due to the difference in drainage. If it wasn't for this vegetable, there would be no human life in the Desert Angel territory.
One of these vegetables was acquired by the unnamed robot and turned into an Idea of a Food Tree. Some might also have been smuggled by the slaves that were freed from that camp. If they did, then these might be present on Xanthe 3, Daenc Hydrax 4, and The Land of Gravity and Quills.
