Tentalus is easily one of Skyward Sword's more menacing enemy creatures--he single-handedly destroys an entire dungeon just minutes after Link clears it. He's equipped with two massive, death-dealing tentacles and dozens of smaller ones, all of which can break through walls and floors, smash anything in their path, and constrict the life straight out of a victim. Sounds like Link's toughest challenge yet, right?
Not really. Newly armed with a MotionPlus-powered bow, Link's accuracy is almost scope-like, making a direct shot to Tentalus' oversized eye a piece of cake. From there, it's just a matter of waiting for the huge sea beast to temporarily collapse within striking range, and slashing the living daylights out of its peeper. It's a thrilling encounter mainly because of how frighteningly gargantuan the enemy is, but when it comes to difficulty, Link has dealt with far worse (the aforementioned motion controls, for example).
