Black and White discover that they can mix to make Grey, and once that happens, they mix with Grey to make Dark Grey and Light Grey, creating a whole family of shades. The Greys' main habitat is the city, which is also where their pet elephants are usually spotted in. They all love rainy days, because they usually dance and play in the rain! The Greys can't speak verbally with words, but they can squeak and squeal!
