Just as a side note: Those are resources he’s trying to gather for a build behind the giant cat statues. 
Also “a few thousand” is a bit understated.
Balkinus already collected way more than that but since most of the build will use bricks for variation (blockchanger chisels, yay!), the conversion rate during the crafting process is poop and the build will be pretty large to keep up with the statues… you might be able to do the math.
We’re farming as much and fast as we can but every bit of help is appreciated. (And I think 3c per stone block is a really decent offer 
)
Also Paka was kind enough to change some colors so we can farm them on her high tier planets. If you tend to farm there as well be aware you can get some additional profits if you drop spare stones from there at Balkinus’ place.
About how to get there since Balkinus doesn’t have a direct portal to TNT yet:
The easiest portal route seems to be “TNT main hub → Ultima hub → Niia Zed Ka → Argamemnon’s portal (to the right hand of where you enter Niia zed Ka)”
