Bing and Pando experiment with Bing's toy train on the Fun Fort in the playground. The train is good at going over bridges and brilliant at going down the slide. But when Bing slides it off the roof of the play house, the train crashes and breaks. Bing is upset until he realises that the pieces fit together to make something completely different.

Bing takes his Hoppity Voosh toy to the park to see the ducks and play on the slide. But when he steps in dog poo and heads to Amma's house to get cleaned up he leaves Hoppity behind. Amma helps Bing to focus so that he can remember where he went and retrace his steps to find Hoppity.
