Dodongo Snakes

A pair of Dodongo Snakes serve as the mini-boss of Key Cavern, the third dungeon in The Legend of Zelda: Link's Awakening. They are also seen in Face Shrine, the sixth dungeon. They look rather like black eggplants with mouths at the base.

Strategy
Just like the Dodongos for which they are named, Dodongo Snakes are destroyed by the use of bombs. Link must feed each snake three bombs to defeat it. He must carry a sufficient number of bombs into the room with him before the battle begins; if he leaves to acquire more, he must start the battle from the beginning when he returns.

Glitch
There is a glitch in the game which sometimes removes the necessity of this particular battle. Although not guaranteed to happen in every game, it will sometimes come to pass that if Link leaves the room and returns, the Dodongo Snakes will be dead when he comes back.
