They have the size of a small ball or a fluffy colt, its body covered with fluffy leaves and a short sprout of leaves on its head.
The difference is its feet, the back feet is more greenish and which used to ‘root’ itself on the ground. The front feet is strong enough to dig in soft soil to “plant” itself. Once it settled on a patch of land, it will be permanent, transfering is another way taking care of this garden fluff just bae with its constant nagging when you transfer it.
Potato foals would crawl out of the ground when nearing maturity (when its potato skin begins to grow small fluffy leaves.)
Mostly will go look for its own area to “plant itself” or the farmer can dug them up and plant them on a diff pot or patch of land.
Harvesting can be the same as regular potato, hold the main stalk of the fluff and pull, or dug it up take the foals and cover again the mare’s lower part to have her “breed” new batch of foals.
Potato foals cant feel anything when you cleaned and skin it light brown skin, its contant chatter for its mother mostly, some would chop of the head and thats it.
Like plants they are more into rich soil and sunlight.
