Moldorm (デグテール Degu Tēru?, Big Tail) is the boss of Tower of Hera, a dungeon in Hyrule in The Legend of Zelda: A Link Between Worlds. A stronger version of Moldorm later appears as a mini-boss in Lorule Castle. Both versions appear as challenges in the Treacherous Tower mini-game.
The battle with Moldorm is largely the same as A Link to the Past's Moldorm. It will erratically crawl around the battle area, bouncing Link away if he touches it, and can only be damaged by hitting its tail. Unlike its original counterpart, however, this incarnation will not regain health if Link falls down, and moves less quickly, probably to make the battle easier.
