Tombliboo Ooo is building a tower of bricks. Here comes Tombliboo Eee, she spots her favourite brick in Ooo's tower. Be careful Tombliboo Eee - she knocks over Ooo's tower trying to get her brick. Ooo is upset about his tower and starts to play sad music on the Tombliboo piano. Ooo's sad music makes Eee and Unn sad as well so they join in.
The Tombliboo's sad music makes everybody else in the garden sad. Tombliboo Unn decides to start playing the Tombliboo drums. What happy drumming. The Tombliboos begin to play happy music which makes everyone happy again.
