This is a fun little build I messed around with. Not too showy, but a lot of fun.
I gave it a green color, so I guess it's good for forested or swampy worlds: which I guess is where they were used most anyways, since they were nicknamed "muckrakers." But as you can see, I didn't have as many green elements as I would have liked. Oh well, what can you do?
The neatest part for me was adding the red light-up brick. A bit challenging, but worth it. It makes the droid a whole lot more sinister.
