Mort, Wart, and Gort, collectively known as Orson's Brothers, are the main antagonists in U.S. Acres. They are (unsurprisingly) the elder brothers of Orson and enjoy picking on him or bullying him whenever they visit, and have also been known to steal the farm's vegetable crops. However, they are not particularly smart, allowing Orson and his friends to outsmart the pigs and send them running all the way back home. More specific information on each brother can be found on their respective pages.
