Manji

Manji, or simply Level 3, is the third dungeon in.

The Dungeon Entrance
In the First Quest, it's entrance is located within the central area of Hyrule, just west of Link's starting point. In the Second Quest, the Manji dungeon's location is moved, and its entrance is therefore beneath a pond atop a green hill in western Hyrule, requiring the Flute from the Moon dungeon (the former occupant of that spot) to gain access.

First Quest
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 green. Darknuts patrol the rooms, so Link must be careful here.

The main Dungeon Item of this dungeon in first quest is the Raft, which is used only in the overworld of Hyrule. The boss of the dungeon is Manhandla, who guards one of the Triforce pieces.

When looked on a map, this dungeon resembles the shape of a manji. This is the Japanese term for a swastika; which historically marked the point of Buddhist temples. This is therefore seemingly the first Zelda dungeon to be equated to a place of worship such as a temple or shrine.

Second Quest
In the Second Quest,the dungeon's walls and floors are changed into a dark and deep shade of blue, making it more similar to the Moon dungeon of the First Quest. Despite it not being the first dungeon, it is actually pretty small in size, but now greatly differs in difficulty.

The Dungeon Item of the dungeon is replaced by the Magical Boomerang, which is guarded by a room full of blue Goriya. Curiously, the dungeon's boss, a trio of Dodongos, guards not the Triforce but the compass; after killing them, Link must still battle a group of red Goriya in the next room before he can claim the Triforce piece.

Additionally, the Manji in the second quest is the first dungeon to have a 'friendly' Goriya, who will grumble and will not let Link pass unless he gives him some food.

The most noteable difference in the shape of this dungeon was that it is changed from the shape of a manji into the shape of the letter L, (although not a pure L, as there are two more rooms which are disconnected from the rest of the dungeon), sharing a common link with most Second Quest dungeon that use letters to make up a word. When the shapes of the Lizard (Letter Z), Eagle (Letter E), Manji (Letter L), Snake (Letter D), and Moon (Letter A) dungeons are listed in that order, they spell Zelda.
