Thanks you two (I see another anon also got stuck here earlier in the thread).
After I beat SplintSis I got to picrel, but I couldn't figure out how to go up, so I just went left, and even though wormways.
After going back to picrel from ya'll advice, I now see there's a tiny ledge there under the flower that I missed.
I have wallcling now. Thanks!
