Why Chameleon Changes Colour

You see there was a time when Chameleon wasn't bright and colourful at all. In fact Chameleon was rather dull and grey, like a rainy day. One day when all the animals are playing games and sheltering from the rains Chameleon decides to slip away because he feels boring. Butterfly comes across Chameleon sitting sadly on a rock and shows him a rainbow. Chameleon can't resist and stands on the rainbow, and he turns red and yellow and pink and green! Chameleon soaks up all the colours of the magical rainbow and now Chameleon can be any colour he wants!
