Before R30 camps at least, 1 stars CAN have red/orange mobs when they appear in groups. A group of say green mobs becomes red. As you kill each ob the color degrades... You more than likely clicked 1 star, the mobs (depending on type... gnats, devlits, and cactuars are still nasty) should have scaled down as you killed their friends.
