The Willies (also known as the Willie Brothers) are major antagonists in Disney's 45th full-length animated feature film Home on the Range. They are Alameda Slim's innocent but bumbling nephew triplets and henchmen. Their names are Phil (red bandanna), Gil (green bandanna) and Bill (blue bandanna).
They were voiced by Sam J. Levine.
The Willies are extremely slow, funny, dumb, stupid, comical, innocent, and outrageous. They don't seem to be very evil in the slightest; just very dimwitted and unintelligent. They are not malicious and manipulative, like their uncle and don't possess any evil intention to be like him.
However, the brothers do have some level of endurance, such as withstanding multiple slaps and hits from Slim and seemingly recovering from being kicked by Slim's boot.
The Willie Brothers are first seen when Maggie, Mrs. Calloway and Grace arrive at a cattle drive. When their uncle arrives, they greet him by saying, "Howdy, Slim!" Slim, however, silences his nephews and slaps them across the face before explaining that they have work to do. The Willies then manage to steal many herds of cattle during the "Yodel-Adle-Eedle-Idle-Oo" sequence, thanks to Slim's yodeling, as it subdues any bovine that hears it save Grace (due to her being tone deaf).
The Willies are later seen at Echo Mine, their uncle's hideout. One of them is seen playing with a cootie catcher. When Slim arrives, he shouts at them to get their attention, and reveals his plan to buy Little Patch of Heaven after he auctions off all the other farms in the vicinity. When Slim dons his Yancy O'Del disguise, the Willies all exclaim in fear. One asks, "Who are you?" and another asks, "What did you do with Uncle Slim?" The first Willie tells the disguised Slim to put up his dukes, only for Slim to painfully squeeze his nephew's hand and slap him across the face before telling him it's Uncle Slim, and that he uses this disguise to sneak in the auctions and buy all the land. One of the Willies is later seen trying on Slim's disguise, causing his brothers to react in the same manner as before.
Later, Mr. Wesley arrives to buy the herds of cattle that Slim and the Willies have stolen. At one point, they manage to rope Pearl's farm cows, who had journeyed to Echo Mine to try to capture Slim and use the reward money to save their farm from bankruptcy. However, the Willies are soon thwarted by Buck and Lucky Jack, who also manage to free all the stolen cattle that were harbored by Slim and the Willies. During the ensuing battle, Lucky Jack defeats one of the Willie Brothers by throwing a horseshoe from Buck at him. Another Willie comes after Buck with a shovel, but the latter manages to defeat him by using martial art skills. The three cows also join in the fray and battle the Willies together. The defeated Willie Brothers were eventually locked in a train cart along with Rico and Mr. Wesley, who were also beaten up by Buck, Lucky Jack, and Pearl's cows. It's completely unknown what happened to them afterwards, but it's presumed that thw Willie Brothers along Mr. Wesley and Rico ended up being arrested following Slim's arrest for their crimes, although in case they were never found (implying the the cows along Buck Lucky Jack closed the train cart with indurance), they possibly starved to death locked at the cart.
