A Boy and His Blob Wii ANB files

I stumbled on some of the anb files for this game while organizing my computer, and to my surprise they were actually pretty easy to read.



The problem, however, rises with the trademark wayforward piece image together from texture system.


Unlike the other wayforward games I've worked with, this one is really confusing.
I was wondering if someone could take a look.

Here is the anvil file: https://www.dropbox.com/s/q1iv1gn3s1pokgs/hud_anvil.anb?dl=1

The area of interest is at 0x2C
That's a coordinate table with like 64 bytes per entry
Anvil has 3 entries
Those coordinate have to somehow point to the locations on that texture. I can find no correlation.

I feel like the 0xC1 and 0x41 are flags that tell you to do something to the next byte, but I don't know what.
That's about as far as I've managed.

Thank you for your time
