There are many Dekus in Zelda...
its a creature in tfe legend of Zelda
It was cursed by Ganon.
The Deku Nut is an item found in Super Smash Bros. Brawl, but originally it is from The Legend of Zelda Ocarina of Time.
roll into it -_-
Queen Gomah, The spidery thing in the basement of the deku tree.
You mean Queen Gohma? Stun her with a Deku nut, slash her eye, when she climbs, shoot her eye with the slingshot, stun her when she falls, slash her eye again, that should do it.
After you beat the Deku Tree, you go to hyrule castle. sneak past the guards. then you find her as young link. as an adult, well when you see Sheik, he IS Zelda
you complete either left or right garden cant remember
I'm pretty sure it's 1,3,2.
If you mean Zelda, you don't find her in Majora's Mask. However, You can find the Deku Princess after defeating Oldowa, the first boss of the game in Woodfall Temple.
Its after the Temple in the Swamp. You need to go outside the deku palace. At the left side of the palace there is a cave with a deku and you need to follow him fast and do not fall in his traps! Then at the end he will give you the mask.
you do not upgrade nuts. only seeds.seeds!:lost forest.turn right. hit the very middle of the target 3 times. a deku sprout will give you a better seed bag.
