Episode 5

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. The team have the fun job of mucking out the elephants - but they get rewarded for their hard work. Skipper takes Nature Chris on a walk in a peat bog with Green Balloon Club member Jake, but Nature Chris doesn't know they have a wet surprise in store for him.

Green Balloon Club members Nimah and Tara introduce some of their chickens, while Jelly and some of her Green Balloon friends, Clavin, Paulena and Murray, are staying up late to try and film hedgehogs in the garden. And of course the Green Balloon Club is never complete without a song - a special zoo song.
