In the room above the convenience store, garmonbozia is seen in plates and bowls on the Formica table.
BOB feeds on fear. Notably, he fed on Josie's fear. The White and Black Lodge open respectively with love and fear and with imperfect courage (fear), the Black Lodge would annihilate one's soul.
When Donna Hayward took over Laura's place in the local Meals on Wheels in the hopes of finding out more about who killed her, she had to deliver a meal to Mrs. Tremond. Mrs. Tremond saw creamed corn on her plate and told Donna angrily that she asked for no creamed corn. Mrs. Tremond asked Donna if she saw creamed corn on her plate and Donna said yes. Then she asked her the same question again and she hesitated, then said no. Donna then looked over at Mrs. Tremond's grandson, who was sitting on a chair in the corner of the room and holding the creamed corn in his hands.
Cooper's doppelganger ate creamed corn in a restaurant. He later vomited garmonbozia, and it proved to be poisonous to humans upon exposure, sending a highway patrolman to the hospital. Dougie Jones also had some corn kernel in his vomit.
Loosely speaking, "garmonbozia" is a negative spiritual energy of pain and suffering, or perhaps created from pain and sorrow. The bad spirits who inhabit the Black Lodge, such as BOB, intentionally manipulate people in Twin Peaks into negative situations in which they will experience emotional pain and sorrow, in order to generate garmonbozia. This influence can be direct, such as when BOB possesses people's bodies to commit murders, but it also seems to be a pervasive indirect influence on the entire town, which may account for the eccentric or obsessive behavior of many of its inhabitants. Garmonbozia is negative energy, and has no real physical form: it only appears as creamed corn during visions of the Black Lodge because this is a form humans can comprehend. It takes the form of a food product because it is a food of sorts to the evil spirits. Similarly, the "Man From Another Place" isn't a real dwarf who exists physically, he simply appears in this form so Cooper can comprehend him.
Behind the scenes Edit
In the script of episode 9, the grandson does not teleport the creamed corn away but makes magic tricks involving playing cards.
In the shooting script of the movie, the word "garmonbozia" is only used in the final scene in which BOB heals Leland and gives garmonbozia to Leland. Interestingly, it is explained as "corn" instead of "pain and sorrow".
