Wussywat is playing with his favourite toy train. When he meets Ird at her tree he wants to borrow her scarf, but she won't let him unless he swaps something. Duckadile wants to blow his horn and be the driver but Wussywat is the driver.

When Wussywat arrives at the shed Ortus shows him Uncle Urtle's ticket collection from his world tour and tells him about sharing. Wussywat has the idea to do a world tour of the garden by making a train everyone can go on. All aboard for Wussywat's sharing game! Choo choo! What a clever cat.
