Grotatoes

Grotatoes are a new species of plants (specifically potatoes), created by Tennis Ball. They first appeared in Welcome Back. They were made for Fries to make more fries for him. They are modified to grow in locations such as Yoyle City, whereas normal potatoes can't grow in Yoyle City because of the low amount of sunlight.

Not much is known about Grotatoes, except for the fact that according to Tennis Ball, they may induce some side effects.

Appearance
Grotatoes look like normal potatoes with purple dashes on it.
