This is a British television series airing on BBC particularly aimed at babies and toddlers.
The Teletubbies are aliens with television screens in their tummies who live in Teletubbyland. In this series, there is Baby Sun in the sky who watches them. In the Tubbytronic Superdome, there is a vacuum cleaner called "Noo-Noo" that tidies up after the Teletubbies. They enjoy various activities and sometimes play around doing nothing. Their favorite foods are Tubby Toast, which is round and in the picture of a happy face, and Tubby Custard, which is pink and is slurped in a bowl through a strawlike tube. In each episode there is a video showing how children live all over the world, and the Teletubbies always want it repeated.
