Lemongrab is an earldom ruled over by the Earl of Lemongrab and his clone. It is located in the Land of Ooo and is a subordinate territory to the Candy Kingdom, which means that the Earl of Lemongrab has to submit to the authority of Princess Bubblegum. The earldom consists of Castle Lemongrab, the small mountain on which it rests, and the surrounding area of trees and grass. After the events of "All Your Fault," it is only a few minutes away on foot from Princess Bubblegum's castle.
Upon learning of the accident that causes Princess Bubblegum to become younger than him, the Earl leaves Lemongrab to rule the Candy Kingdom. Once she reverts to her normal age, however, she fires him, and he returns to his castle. The Earl remains in his castle for over a year before returning to the Candy Kingdom to seek out companionship. After leaving again for three days, he comes back for one day in which he tries to be with people again, and Princess Bubblegum unsuccessfully tries to show him the ways of the Candy People. Lemongrab panics and once again leaves to return to Castle Lemongrab, where he then lives happily with his clone, Lemongrab 2, and their Lemon Children.
Lemongrab again appears in "Too Old," but this time it is in a state of disrepair. Also, the citizens are now closer to slaves than anything else because they all wear collars that electrify them whenever the earl presses a button on a remote. Finally, in his possibly final appearance, Lemongrab 2 detaches the collars and gives Badlemonnohope some final words before being devoured by Lemongrab.
