Grotatoes are a species of potatoes created by Tennis Ball. However, they only appeared in Welcome Back so far. They were made for Fries in order for him to make more fries for himself. They are modified to grow in locations such as Yoyle City, whereas normal potatoes can't grow in due to the low amount of sunlight.
Not much is known about Grotatoes, except that they can grow with less sunlight and contain unknown side effects.
Grotatoes appear to look like normal potatoes with purple (Yoyle) dashes on it.
They come in green-yellow packets including just seeds, as shown in the text below the title on the bag.
- The appearance of a Grotato was revealed by Cary on the HTwins Central.
- The Grotatoes appear to have worked, since Fries is shown to have all of his fries back in BFB.
- However, it's possible he simply died and regained his fries.
