When Mum gets Dad a lovely new spacesuit, Cosmo wishes she could be a different colour, something special. Their next mission is a special one – Cosmo, Dad and GIL must travel to Mars to search for water. As they make their way across the red rocky surface of Mars, they find themselves engulfed in a storm of red dust. Cosmo gets lost and can't find Dad anywhere. With some quick thinking, she manages to find him and when the storm settles she sees that she is now a different colour. She is covered head to toe in red dust!
