Level 4

Snake Labyrinth (Or simply Level 3) is the third dungeon in The Legend of Zelda.

First Quest
In the first quest, it's entrance is located within the lake area of central Hyrule. The raft, that is obtained in the previous dungeon, is required to reach this dungeon's entrance. The interior of this dungeon appears to be made of stone bricks, like most dungeons in The Legend of Zelda, with its primary color being dark yellow.

The main dungeon item of this dungeon in first quest is the Stepladder, and unlike most dungeons in The Legend of Zelda, the Stepladder is needed to progress further within this dungeon. This dungeon is also the first dungeon in the first quest to have a mini-boss, Manhandla, whereas the main boss is Gleerok who guards one of the Triforce pieces.

When looked on a map, this dungeon resembles the shape of a snake, hence the dungeon's name.

Second Quest
In the second quest, the Snake Labyrinth's entrance was moved to another location, and is now located in the maze area of Lost Hills. It's entrance, in the form of a hidden stairway, is under a stone which requires the use of the Power Bracelet to be moved. Like most dungeons in the second quest of The Legend of Zelda, this dungeon now differs in size and difficulty. Additionally, the walls and floors of the dungeon were changed into the color green.

The main items of this dungeon in the second quest are the Raft and the Magic Book, although only the raft is required for later use in the game. Additionally, this dungeon offers an old man who requires Link to pay 50 rupees or give up one of his heart containers from his health bar in order to progress further. If Link gives up 'his life' as the man puts it, he will be unable to get it back.

This dungeon also has quite a few mini-bosses compared to previous dungeons, having a room with a Digdogger, a room with Aquamentus, a room with a single Dodongo, and another room with three Dodongos. Though despite Digdogger appears as a mini-boss in this dungeon, another Digdogger also appears as the main boss who guards one of the Triforce pieces.

After Link enters the room with the Triforce fragment, he must not retrieve it yet; instead, he first has to keep walking to the right to find some more rooms, and then the Raft. If Link takes the fragment first, then he'll be warped to the game's overworld, but won't be able to find the next dungeon without first exploring once more the one he just cleared so that the Raft is found. This is because the fifth dungeon is on an island, and Link is unable to swim on his own towards it.

The most notable difference in the shape of this dungeon was that it was changed from the shape of a snake into the shape of the letter D, sharing a common link with most second quest dungeon that use letters to make up a word. When the shapes of the Lizard Labyrinth (Letter Z), Eagle Labyrinth (Letter E), Manji Labyrinth (Letter L), Snake Labyrinth (Letter D), and Moon Labyrinth (Letter A) are listed in that order, they spell Zelda.
