Sizzlers are a common pet. Sizzlers are born of human fires, and so are drawn to them. If they are charged*, they can create fire themselves. They are extremely playful, especially with humans, but will play with other animals, or things too. *To charge, Sizzlers need to play in a fire in the house of the fire that created them. If their "charge" wears off, eventually their warmth will die out and they'll turn into dust. First one is Charged, second is fading They are always smiling, and will still be playful, even if they are fading and feeling it. They will always show their love to the masters of their home.
