How to get Articuno?

Checked the previous posts on the matter and the answers linked to unavailable videos/images.

I know where the wall is, I know where to use hiking boots, I know which boulders to push and break. The rare candy is in the way so it doesn’t look like there’s a way to get to the wall.

Any help, please?

And not 10 minutes later I realized what to do. You get the rare candy FIRST, then reset the puzzle, then you can get to the wall by going around the other side to finish pushing the last few boulders. Hope this helps someone.
