Inside the Deku Tree

Inside the Deku Tree is the first dungeon of. It is the interior of the giant guardian of the Kokiri Forest. When it contracts a mysterious disease, Link must venture inside to destroy the Tree's scourge and to break Ganondorf's curse. It is infested with parasitic creatures, the main one being Queen Gohma. This dungeon contains the Fairy Slingshot.

Entrance to the Tree
The Deku Tree is found east of Kokiri Forest. To reach there, however, Link must show Mido,who is blocking the way, the Deku Shield and Kokiri Sword. After that, Link approaches the dying deity, who talks to him about his situation, and enters.

Themes and Navigation
The Great Deku Tree contains five floors, of which three are over the surface and two are underground. The first three floors resemble a central circling room that, with the exception of the first floor, have branched rooms where Link can find various goods. The two basements are only accessible when Link jumps from a very high spot to the center of the first floor's entrance; most of the puzzles in these basements require Link to kill any enemy or destroy thick webs through the use of fire. The final puzzle appears in the form of three Deku Scrubs which must be defeated in the correct order (second in line, third in line, and first in line) to face the boss, Gohma. There is no mini-boss in this dungeon, although there are two individual Deku Scrubs in the dungeon, as well as the aforementioned group at the end.

To obtain all the Gold Skulltula Tokens, Link must return to the dungeon after getting Bombs and the Boomerang.

Master Quest
In the version of the game, besides the obvious change in the puzzles and Gold Skulltula locations, Gohma Larvae now appear all over the dungeon, along with Keese and some Big Deku Babas. There is a Business Scrub that sells a Deku Shield, and the Deku Scrub that reveals the code for accessing the boss's room is missing and has been replaced with a Mad Scrub. The slingshot and compass locations have been switched.

Trivia

 * The sealed room in the basement of the dungeon containing the final Gold Skulltula does not appear on the map until it is visited, even after Link collects the Dungeon Map. This is the only time in the game a dungeon map does not show the entire dungeon. It was fixed in.
 * Inside the Deku Tree and Dodongo's Cavern are the only dungeons in without their own music theme. The Secret Grotto theme is heard Inside the Deku Tree.
