Entrance to Level 4
Level 4's entrance is in the same location as the original Level 4 in The Legend of Zelda. It is located on an island accessible only with the Raft.
Moldorms make their first appearance in Level 4, along with Like Likes and Pols Voices. The Ocarina, which replaces the Flute from the original The Legend of Zelda, is found in a staircase room (which originally contained the Stepladder). There is also a Bomb upgrade granted by an Old Man that allows the Player to carry 12 Bombs. At the end of Level 4 is Digdogger, who guards a piece of the Triforce of Wisdom and a Heart Container. Completing the Dungeon also eliminates the tornadoes in the Lost Woods, enabling the hero to obtain the White Sword.
The layout of Level 4 forms an "I", following the Dungeon pattern that spells out "St. GIGA".
