In the Legend Mode mission The Water Temple, after encountering Fake Zelda inside the Water Temple King Dodongo is summoned to attack your allies. At this point Darunia and Ruto appear to fight the monster, telling you to stay where you are and finish the mission while they take care of it. Once this happens, don't finish the mission and instead go to where King Dodongo is to see that rather than the usual yellow Dodongo that appears everywhere else in the game, this mission (and only this mission) uses the black-scaled version with large crystals on its shoulders, which appeared in The Legend of Zelda: Ocarina of Time.
