The Bridge of Eldin was a location in The Legend of Zelda: Twilight Princess, as well as a stage in Super Smash Bros Brawl, and later showed up in in Hyrule Warriors. Oh yeah, also it's in Smash 4.
The Bridge of Eldin is where Link fought King Bulbin for the kiddies of Ordon Village or something, I forget, haven't played Twilight Princess in ages. In Smash, it's one of the most basic stages ever. It's just a flat surface. But before you start masturbating to it, competitive players, I have some bad news. It has walkoffs. So no competitive battling. And even then, the stage is also home to King Bulbin, who will ride around the stage and will drop a bomb, blowing up a portion of the stage. But not the walkoffs. When this happens, TP Link and Midna go on a huge sidequest to go to Zora's Domain to get the piece of the bridge back (but they first go to Death Mountain and have to deal with the Gorons and have to go through the Goron Mines and lots of other stuff to defrost the lake to get the bridge.) The bridge will then be brought back via a Twilight portal. Until King Bulbin blows it up again. King Bulbin is an asshole.
Also, on this stage, Jigglypuff has a crazy glitch, at least in Brawl. If you use Jigglypuff's final smash in the broken section of the bridge while the bridge is being repaired, Jigglypuff will stay huge. It's not particularly useful, but it's still pretty funny.
