Day Three - Farfetch'd has always been one of my favorites. It carries a leek with it wherever it goes - but in all of the games it's never explained why.
I'm starting to think of the motives behind the people who created these characters. This one seems to have been an attempt to reference the way certain species of animals use their habitats, but the fact that the supposed in-game scientists don't understand why Farfetch'd carries a leek is kind of strange to me.
Like some guy who didn't fully understand zoology in the creative department at Nintendo was just like "it should carry a leek, and they ran with it.
