Have you checked out the bar (forgetting the name) next to Nurbs (on the Astroid)? I know there's some there.
And head into the bathroom in the back (keep walking right once you enter). More are there.

Nurbs Landing has the bar Nurbs on it (guy in Chewbacca mask), with the bathroom hallway full of backer pictures and the Keronian Underground list at the end. I can't find a way into the actual bathroom, it just stops letting me walk right. Is there a different place that I'm skipping?
(thanks again for entertaining all this)
Yeah - that's the area I was thinking of. (You can't actually go into the bathrooms... er, that I am aware of... there's just a sign that mentions the bathrooms are in that direction).
And you've gone back to all the places - guys from Andromeda's landing? The desert, you have - because you mentioned the worm. Um, Crash's place - outside and inside?
Trying to think (I don't have them all myself, but been collecting them) - I can't think of any that are specifically "hidden" except the asteroid ones?
I made a post on Reddit (5 upvotes, woo!) that lists out what I found, just to make it easier to keep track. Maybe our Venn diagram isn't a total circle.
