Tinky Winky is out for a walk when a voice trumpet rises. The voice trumpet repeats the word yellow and Tinky Winky is intrigued and repeats the word after the voice trumpet. A yellow cloud appears in the sky and floats above Tinky Winky. Then the Teletubbies watch a group of children looking at the colour yellow. They look at various yellow objects and paint a big yellow picture. The Teletubbies play a hiding game. The Teletubbies dance a Bumps-a-daisy Dance.
