Spring is on the way. Ant has found his first ladybird of the year; it looks as if they are coming out of hibernation. Lily-Rose's hyacinth has bloomed and Green Balloon Club members Malikah, Centaine and Zahra are finding first buds and shoots where they live. Sky starts off a bean seed experiment whilst Jelly is visiting some friends who are working in a kitchen garden.

The Green Team find out about the life cycle. Ant brings in some pupae that he is watching, hoping that they will soon hatch into butterflies. Green Balloon Club members Maisie, Christopher and Jada find frogspawn in their local pond, while Jelly and her friends check out the bird life on the estuary. Jay learns about puffins.

The Green Team are going tracking. Every creature makes a different print, but can they recognise them? Green Balloon Club members Joanne, Jack, Jonathan and Niamh are on the East Anglian coast looking for a beautiful bird called an Oyster Catcher. The Ground Crew set off on a tracking mission too and find something quite a bit larger. Cat finds out about Hares, whilst Lily-Rose and Ant make a peacock using their own prints.
