OK, I think I’ve got it!
We have three Navajo words confirmed:
dibeh,
klizzie, and
na-as-tso-si. We’ve also had four tweets in various configurations. If we look at them all:
This was our first hint towards the use of Navajo. Also note the placement of the asterisks, the dashes and the buzzing.
This is obviously an obscured
na-as-tso-si.
Asterisks and dashes again in a similar arrangement to previous. We also get our second clear Navajo word.
There’s those dashes again, and the unobscured Navajo.
I think that this is all supposed to be one string that’s been broken up into several messages, with different parts missing or obscured each time. I think the punctuation is meant to hint at the placement of each word in the full message.
In two cases, we have one long obscured part followed by two asterisks, and then followed by two dashes. In one case, there’s a word between the dashes, and in another there’s a word after the dashes.
Now look at the second obscured component (bzbzzbzbzzz). If we assume each buzz is a syllable, then this matches the number of syllables in na-as-tso-si. I think these are one and the same.
I think the full unobscured message is meant to be:
na-as-tso-si ** - dibeh - klizzie
Ignore the punctuation, and we have:
M S G
Aaaand here’s where it leads:

Edit: I’m pretty sure the green symbols are a jigsaw of some sort, stitching them together now to see what comes out.
