Level 4


 * For this Dungeon in, see Level-4 (BS The Legend of Zelda).

, also stylized as Level-4, and known as Snake, is the fourth Labyrinth in.

Entrance
In the First Quest, its entrance is located within the lake area of central Hyrule. The Raft, which is obtained in Level-3, is required to reach this Labyrinth's entrance.

In the Second Quest, the entrance to Level-4 is a hidden stairway on the mountain maze in northeast Hyrule. It is located under a stone which requires the use of the Power Bracelet to be moved.

First Quest
As the title of the Labyrinth suggests, its Map resembles the shape of a snake. The interior of this Labyrinth appears to be made of stone bricks, like most Labyrinths in The Legend of Zelda, with its primary color being dark yellow. This Labyrinth introduces dark rooms that Link cannot see in without Fire. To create Fire and illuminate the room, Link must either use a Candle or a Magical Rod in combination with the Book of Magic. It also introduces two enemies, the Vire and the Like Like. The main Item of this Labyrinth in First Quest is the Stepladder. Unlike most Labyrinths in The Legend of Zelda, the Stepladder is needed to progress further within the same Labyrinth it is obtained in. Level-4 is also the first Labyrinth in the First Quest to have a mini-boss, which is Manhandla. The main Boss is Gleeok, who guards one of the Triforce Fragments. This Dungeon has less Keys than needed to unlock all of the doors in the Dungeon, as there are four Keys and five locked doors. Link can unlock all of the doors by obtaining one of the extra Keys in Level-2 or Level-3 or by purchasing a Key from a Shop.

Second Quest
In the Second Quest, the walls and floors of the Labyrinth are green, being similar in color to the First Quest's Level-3 and Level-5. The main Items of this Labyrinth are the Raft and the Book of Magic. Link does not need the Book of Magic in order to collect all of the Triforce Fragments. This is the first Labyrinth in the Second Quest in which colored Bubbles appear, with the red ones being able to prevent Link from using his sword indefinitely until he touches a Blue Bubble. This is also the first Labyrinth in the Second Quest to include an Old Man who requires Link to pay 50 Rupees or give up one of his Heart Containers in order to progress further. If Link gives up a Heart Container, there is no way to get it back. There is also an Old Man in this Labyrinth who will increase Link's Bomb capacity for 100 Rupees. This Labyrinth has more mini-bosses than previous Labyrinths in the Second Quest. It contains a room with a Digdogger, a room with an Aquamentus, a room with a single Dodongo and another room with three Dodongos. Another Digdogger also appears as the main Boss, who guards the Labyrinth's Triforce Fragment. There are additional rooms to the right of the room with the Triforce Fragment, with the Raft located at the end of these rooms. If Link takes the Triforce Fragment before exploring these rooms, he will be warped to the Overworld. However, he will need to navigate the Labyrinth again to collect the Raft because it is required to access Level-5.

The most notable difference in Second Quest is the shape of this Labyrinth, changing from a snake to the shape of the letter "D." The Maps of the first five Labyrinths in the Second Quest each symbolize a letter, spelling out an anagram for "ZELDA."
