The Teletubbies live in a world full of fun, love and laughter in the rolling green hills of Teletubbyland. Playing, dancing and singing in their modern, subterranean Home Dome, the Teletubbies are joined by a colourful cast of characters including hoover-like pet the Noo-noo, the Tiddlytubbies, the caring voice trumpets, the temperamental Tubby Toast machine and the whirling, twirling Tubby Custard Ride.
