Early on in the game, as a callback to Gen 1, a trainer will trade you a Farfetched for Generic Route 1 Bird Pokemon. Later on, after earning 6 or 7 badges, the person will still be there. If you talk to them with a level 30 or higher Farfetched in your party, he will express regret for scaming you earlier, and decides to give you a new item to make up for it. He gives you... the Sauce Stick. It doesn't change the Poke's stats by much, but it gives him CRAZY EVs on leveling. I mean, INSANE. Although not to gamebracking levels, but to still fairly powerful levels.
