Flora starts moulting and is so embarrassed by her grey stubble that she goes into hiding. Unable to persuade her to come to the zoo, Ziggy transforms the tram into a fanboat to get them across the lake. The resulting wind prompts him to make a feather boa so Flora can cover up. Flora loves it.

Lionel always likes to look smart, so when an accident with Scottie’s packed lunch makes a mess of his safari suit, it’s a major crisis. Miss Emily is able to dry clean the suit, and Ziggy transforms the tram into a bi-plane to get them to the zoo on time.

Miss Emily wants to visit the jungle to see the ‘Empress Emily’, a rare exotic vine named after her by a friendly zoo visitor. Shackleton takes fright at a spider and gets lost in the trees. And by the time he’s found, it’s time to go – without having seen the Empress.

Brian has a cold and wants to stay home in bed, but Miss Emily insists that a mug of her special Hot Lemon Drink will cure him. However, when collecting the lemons causes the tram’s batteries go flat, it takes Brian and a turbine – Ziggy’s latest invention – to generate enough energy to get them to the zoo on time.
