The Teletubbies sit down to eat Tubby Custard, but they stop to watch the children buy different sorts of vegetables. The Teletubbies discover that the sky is blue, the grass is green, and the flowers are red, but Po and the other Teletubbies ask the question – what color is Tubby Custard? (which is Pink) Then Po eats all the Tubby Custard. Po loves Tubby Custard.
