I had something very strange happen to me. I had just hatched my Laserlight dragon, placed him in a large white habitat, and moved a new egg to the nest. I battled with my Music dragon against a Mirage dragon in the arena, and won. After I'd fed a few dragons, I went to feed my new Laserlight. The icon surrounding him was slightly blue and had the Zzz in the corner. I clicked on him, and saw that an option, other than feed, was heal. I saw that he could be put into the spa and healed, although since I have another dragon healing right now, I did not. This dragon has never been in battle, and should not need healing. I'm not sure why this occurred.
