Artaria Area Map and 100% Items GuideComment

>>1 Replying to myself again for anyone else coming here and not finding this item: the hallway directly across the tall room from where the red marker is in my first image post. Speed boost and change shine spark. Shoot this block, morph ball hop in and ball-spark to the left.

Lol I just posted a comment about an upgrade that wasn't listed here that I was having trouble with, then figured it out immediately afterward. Even so, you need to add it to your walkthrough!

I have 93% on Artaria. Found the last secret area but I can't figure it out. You dont seem to have any info about this last item. Is this actually a 100% item guide for artaria? Including a pic of the puzzle area. I'm trying to shinespark(in ball form) from the hallway across this tall room but it's not lined up properly.
