Trousers and towers

In this evening's Night Garden the Tombliboos rode on the Pinky Ponk all the way home where they all took their trousers off. They then began to create giant erections with their bricks. 

All three Tombliboos made a Tombliboos tower of three bricks. Then Tombliboo Unn and Tombliboo Ee worked together to erect an even bigger tower! Unfortunately a very bouncy ball knocked their tower down!

Tombliboo Oo then joined the other two to help erect a larger, stronger tower including an arch. The bouncy ball then knocked the very clever arch down. It turned out that the bouncy ball just wanted the Tombliboos to play with it.  So they did.
