King Bulblin, a mini-boss from The Legend of Zelda: Twilight Princess, is a hazard in the stage Bridge of Eldin. He rides across occasionally to drop bombs on the stage, blowing holes in it. His arrival is preceded by the trumpeting of a war horn. He can also damage characters by running into them. Occasionally, a Bulblin chases after him, but crashes into the bomb if it's still there. King Bulblin can be stunned if you hit him with an attack, he cannot damage you this way.
King Bulblin is the boss of the creatures who kidnapped Ilia, Colin, and the rest of Ordon Village's children. Characterized by his appearance atop a boar-like beast named Lord Bullbo, he encounters Link time and time again. When he loses in his final battle, he pays subtle respect to Link when he says, "I follow the strongest side!"
Lord Bulbo is a Bulbo (a large warthog-like creature) and King Bulblin's mount. He appears, ridden by Bulblin, on the Bridge of Eldin stage in Super Smash Bros. Brawl. Players receive damage when s/he is rammed by Lord Bulbo.
Curiously, unlike Brawl, where King Bulblin destroys the bridge's center; in The Legend of Zelda: Twilight Princess, it was never destroyed by him, it was actually swallowed and transported to the Gerudo Desert by a twilight portal and later Midna took it back to its correct place.
