Potbelly is an Elemental Monster with the Plant element.
Potbelly’s Dawn of Fire Description
This wriggly sprout bursts with energy. It must be loosely tied to a stick as a reminder to stay in its container. A foolish Potbelly that has accidentally rooted in the ground is an absurd botheration to sort out.
You can buy Potbelly from the Monsters menu for 300 Gold.
