Lily-Rose, Ant, Cat, Jay, Sky and Skipper the dog travel Great Britain in a green hot-air balloon. The team are joined by Nature Chris and are having a weather day. They discover different ways of making rainbows and have a look at one of Britain's most brightly-coloured birds. Green Balloon Club members Megan and Ellie are out in the snow showing us how a hedge is planted, whilst Jelly and her friends are down on the farm to meet some racing pigs.
