The GameCube controller for Super Smash Bros. Ultimate might be sold out all over the place, but you don't need it to dominate the competition with your favorite fighter. All you need, it turns out, is a bunch of bananas. A Twitch streamer going by the handle ATwerkinYoshi did a little modding after a grocery trip and managed to turn seven bananas into makeshift buttons to play the latest installment of Smash. ATwerkinYoshi's set up hinged primarily on a Human Interface Device (HID) called Makey Makey. The simple tool converts basically anything into a keyboard input.
