The Green Balloon goes on holiday! Lily-Rose, Ant, Cat, Nature Chris and Skipper the dog travel to Northern Ireland, where the children are going to be zoo keepers at Belfast Zoo for the week. Lily-Rose, Ant and Cat help the keepers prepare meals for the zoo animals - but can they guess who they are going to feed them to? Skipper takes Nature Chris on a walk in a peat bog. Green Balloon Club members Katie and Jon show them round and look for the wildlife to be found there. Faye and Cameron in Ballymena show us the vegetables they have been growing in their garden. Sky and a group of her friends make a big animal picture - can you guess what it is? And of course the Green Balloon Club is never complete without a song - a special zoo song.
