The woodcutters of Azalea Town’s Charcoal Kiln. You chase their Farfetch’d in the Ilex Forest in order to get the Cut HM! The anime expanded their personalities by giving them names - Sylvester (the junior) and Yosaku (the master). However, the 4Kids dub kind of spoiled the game reference by calling them father and son, something that was never true neither in the games, nor in the Japanese version of the anime. Despite that, they undoubtedly represent the unnamed NPCs from the game.
