The Gogans are the tertiary antagonists of the Disney and Don Bluth movie Pete's Dragon and are a gang of nasty hillbillies who treat the orphaned protagonist (Pete) like a slave and often abuse him both emotionally and physically - eventually Pete can no longer put up with the abuse and flees, but they pursue him only to get knocked into a mud pit by an unseen force (which turns out to be the titular dragon - named Elliott).
The Gogans are enraged due to the fact they "paid $50" for Pete - they also hate the idea that they may have to actually do work for themselves and thus decide to pursue Pete and drag him back to the farm to fulfill his job as their slave.
The Gogans finally track Pete down to the fishing village where he is being cared for by a kindly lighthouse keeper and Nora, who proceeds to defend Pete from the Gogans - who pursue them declaring their intent to drag Pete back "home" (with their song "Bill of Sale") - however the Gogans are ultimately sent airborne when, in their attempts to pursue Pete and Nora by boat they are rammed by an invisible Elliott, causing them to splash into the water.
The Gogans proceed to make a deal with Dr. Terminus - the other antagonist of the film - who is seeking to capture Elliott for use in medicine, when Terminus lures Pete and Elliott into a trap, the Gogans are there to try and kidnap Pete, however Elliott manages to break free of the net being used to hold him and saves Pete from the Gogans before incinerating their Bill Of Sale, dousing them in a barrel of tar and chasing them away.
The Gogans were not seen after this incident and given their cowardly nature they likely never will be.
