They were found by the Red King centuries ago in Africa, who saved them from predators and cared for them after their mother was killed. To keep them warm, he wrapped them in his spider silk cloak and found that they absorbed some of the magic from the cloak, gaining special powers. They were originally called Sun Cat, Flame Chin and Star, but these names changed when they changed from leopards into cats.
Right now they have become leopards once again and it is unknown if they are currently residing at the Pets Cafe. Originally they belonged to the Red King, but they were lost.
They have shown powers to revive people from the dead, such as Tancred Torsson in Charlie Bone and the Shadow of Badlock. They can also become real flames, hence the names, and a pile of leaves. They also save Henry Yewbeam from dying of hypothermia in Charlie Bone and the Time Twister, and heal Runner Bean after he is attacked by a werebeast.
