are they good or bad? will it eat my zoos or mushrooms? i think what i saw was one of those would it have a little tuff of red in the center coming out of the hole? did a search but didnt get a good look at any. my computer wont load old pictures on threads for some reason,so if someone to post a picture of what this is i would really be greatful
