Yep, it is a bad thing. Oops, I already see 4 bad things. If that was the only "one" it looks like it has already divided twice. They do look neat and the first one we had was treated with the royal treatment and fed on a very regular basis. It got about the size of a fifty cent piece. The rest of the story is that I never have gotten rid of all of the offspring. The main problems are that they multiply rapidly, they travel and they pack a powerful sting to your other inhabitants. Joes Juice will kill them. Nothing eats them. But, they do look cool so I continue to play with fire and when I hit them with Joes Juice I always leave one in some out of the way place, just for fun. So it is a never ending story.
