Potato Gnomes - entities of mostly unknown gender that appeared in Edna & Harvey: Harvey's New Eyes.
In the first chapter, these little things are covering the corpses of dead students with pink paint, smiling and whistling.
In the dream world on a wild west they have their own town. They can be spot all gathered around a fire through which Lilli can communicate with Miranya the Medium. During a minigame with Shaman you are able to see their homes.
In Hot Motigor, they are last seen (as goblins) with the king, waiting for the sound of the horn. Once the NPC Harvey is disposed of, Lilli and friends charge, slashing and killing the king and his army.
Apart from the Shaman, they are all small and look like potatoes with arms, legs and big smiles.
