Gobblegut is a dragon created by Bowser Jr. to stop Mario. He has a huge appetite with his giant stomach, and usually gets stomachaches when he eats something repulsive. That's how he got his belly bulges, which are his weakness.
There is also a fire version called Fire Gobblegut. After being defeated, he moved to place where there was no spicy food to hurt his stomach. The Toads sometimes visit him there as well.
