These are the Element sisters. They have been brought to Earth to save the elements from dying out. Blu is the eldest of the four, she doesn't get along with the second child Cali, who is protecting fire, very much which is not a real shock because they are total opposites. Then, there's Perth and Aurora, the kindest of the four, Perth is saving the Earth element and Aurora is saving the air element. #element #elementchallenge #water #fire #earth #air
