So I know urchins like to take stuff to try and disguise themselfs but I never expected this one. My tuxedo urchin is walking around with a piece of egg crate. I was wondering if it is safe to take it off of it as this was holding a plug of rasta zoa's and I don't have any spare to replace it. I don't even know how it got is because it was under the sand. Please excuse the algae I haven't had chance to clean it off
