Lily-Rose and friends travel Great Britain in a green hot air balloon hearing stories from children. The Green Team marvel at just how athletic some creatures are. Green Balloon Club members from Cardiff show us what brilliant jumpers their local salmon are whilst the balloon is visited by a very athletic little friend: Georgina the ferret. The Ground Crew are on a mission to find out who is the speediest - ferrets or them. Club members Sara and Indigo, set this week's spot, which can be found in gardens, parks and countryside all across the country. Lily-Rose makes a little ferret to play with once Georgina has to go home. And everything concludes with the Green Balloon Flying song - looking at the wonder of bird migration.
