Can't find in Snakemouth the Isau Petal for doctor

[OxY |]

The doctor in the desert outpost is asking me for a "Isau Petal", I must "climb" Snakemouth Den.
I can't find the petal. Where is it?

[unendingEmpathy]

I believe there is an area around the big door spot that has a path to where it is if you use Vi's flying ability

Which door exactly?

[wataniyob]

The first big door you come across, aka the one where you used stones to push down two buttons and then fell down the trap.

There's a spring hidden behind some cuttable bushes that gets you to an elevated platform which you originally used to cut down one of the stones. From there use Vi's ability to fly to the left (you can rest on the door-tops).

Thanks Wataniyob
