To Woodfall!
The passage lands you atop a big, flowery tree back in the Southern Swamp. Before you burrow into the Deku Flower, look up and 
-Target a giant Dragonfly that circles overhead. Defeat this menace with one of Deku Link’s bubbles, being careful not to fall from the tree as you fight.
Dragonfly
Damage: 1/4 Heart
These overgrown insects buzz about the skies, aiming to zap Link with their electric stingers. Block their attacks with Link’s shield or Deku Link’s shell, then counter with Link’s blade (jump attacks work well) or Deku Link’s bubbles (a safer option).
Use another bubble to bring down a second Dragonfly that also flies nearby. Then, use your tree’s Deku Flower to glide to the next big orange tree to the south.
The next tree lies beyond a big rock formation to the south. Glide to the big rock, and then simply walk onto the tree. Use its Deku Flower to reach the north ledge, heading toward a waterfall.
Nice work! Now simply use the ledge’s Deku Flower to glide past the waterfall and land on the adjacent ledge, which features a save statue. Save your progress, and then go through the nearby passage to enter the Woodfall area.
