The programme features four colourful characters: Tinky Winky, Dipsy, Laa-Laa and Po who live in a futuristic dome (the “Tubbytronic Superdome”), set in a landscape of rolling hills. The environment is dotted with unusually talkative flowers and periscope-like “voice trumpets”. The only natural fauna are rabbits (although birds are often heard, particularly blackcaps and wrens). The climate is always sunny and pleasant save for occasional inclement days, with rain and puddles, and snow at Christmas time.
The Teletubbies are played by actors dressed in bulky costumes, although the sets are designed to give no sense of scale. The costumes vaguely resemble large spacesuits, although the Tubbies appear not to wear real clothes. They are instead furry, and have metallic silver-azure rectangular “screens” adorning their abdomens. These screens are used to segue into short film sequences, which are generally repeated at least once. When the series is shown in different countries around the world, the film inserts are to be tailored to suit local audiences. (The British inserts are default).
The Teletubbies have the body proportions, behaviour and language of toddlers. The pacing and design of the show was developed by cognitive psychologist Andrew Davenport, who structured the show to fit the attention spans of the target audience. The repetition of practically every word is familiar to everyone who has ever worked with young children. There was also help from Shatarra Willis the stage manager who helped the show to become a success.
The Teletubbies speak in a gurgling baby language which is the subject of some controversy among educationalists, some of whom argue that this supposedly made-up talk is not good for children. (A similar complaint was made forty years previously about another children’s series, Flower Pot Men). Tubbies are at the stage of understanding speech but not yet fully capable of articulating it, exactly like their target audience. They often simply groan in disapproval in situations where a human toddler would throw a tantrum. The Teletubbies’ catch-phrases are Eh-oh (hello), as in: Eh-oh, Laa-Laa, to which Laa-Laa will respond, Eh-oh, [other Tubby’s name]; “Uh-oh”, a common toddler response to anything untoward; “Run away! Run away!”, especially from Dipsy; and “Bye-bye” at least four times in a row. Laa-Laa, when flustered, will explode with “Bibberly cheese!”, which is as angry as they get. Perhaps the most common exclamation, however, is “Big hug!” which one or more of the Teletubbies will invariably call for during the course of an episode, resulting in an enthusiastic group hug.
All the Teletubbies say “Bye-Bye” three times. The narrator bids each Teletubby goodbye, and they disappear, but reappear a moment later saying “Boo!”. The narrator then says “No”, and proceeds to say goodbye to each Teletubby again. The sun is then shown setting, and the Teletubbies each say goodbye again, before jumping down a hole in the roof of their house. Finally, one Teletubby says goodbye a fourth time- they pop out of a hole in the house and say “Bye-bye!”. For special episodes, and at the end of the “Fun With The Teletubbies” cassette, all four Teletubbies say “Bye-bye” in this way. Many of the occurrences of the show, including the end sequence, and the scene preceding the short film broadcast on a characters tummy were shot only once, and the same scenes are used in each episode.
The surreal environment is an evocation of a toddler’s perception of the world, where they are ordered about and told to go to sleep, while wonderful and mysterious things happen without explanation. A prominent feature of each episode is a radiant sun that has an image of a smiling baby superimposed upon it. The baby in the sun occasionally laughs out loud in short bursts. To adults the laughter does not seem to be in response to any stimulus or humorous developments in the plot line of the episode.
The Teletubbies’ diet seems to consist exclusively of Tubby Custard (which is sucked through a spiral straw bowl) and Tubby Toast (circular toast with a smiley face on it). One of their companions is the Noo-Noo, a sentient, self-propelled vacuum cleaner.
Machines like the Noo-Noo, voice trumpets, and the televisions in the Teletubbies’ stomachs were designed to show small children, who are born into a world surrounded by strange and powerful electronic gadgets, that technology is benevolent and helpful, not something to be afraid of.
