Where is the fire environment hidden on powerpets?

first, you need the night stone, which i haven't done yet. then you can go into the mini city, and go to the mini city slime purifier, and then get the fireglass angel. then go to lisha's quest, but DON"T DO HER QUEST. chat with her, and she will look in ur backpack. if she gets the fireglass angel, then she will give u the fire environment aka ebil environment.
