Thank you, I appreciate the compliment. I'm still working on crustaceans so I am not certain yet exactly how they will function; my goal, though, is for them to crawl around on the seafloor. I've done some tests and they were able to crawl but they were pretty slow. I'm hoping that with more effort I can speed them up and get them steering better. If that turns out to not be feasible, they may have to swim, but I am aiming for crawling, as I think that makes them a more interesting addition.
