Jelly baby

Jelly babies were an English sweet favoured by the Doctor, his fourth incarnation in particular. The Doctor often offered them to companions and others he met on his travels.

Behind the scenes
Jelly Babies are a real-world product sold under that name since 1953 (existing long before their association with Doctor Who), and under other names many years before that. They are similar to gummi candies.

On a number of occasions, the Fourth Doctor offered "jelly babies" when in fact he was holding another kind of sweet, such as. (TV: The Sun Makers, Image of the Fendahl)

On Tom Baker's official website, an overview of Tom Baker's tenure as the Fourth Doctor by writer Nicholas Pegg claimed that the original script of The Face of Evil involved the Fourth Doctor threatening the tribesmen with a knife. Feeling that such an act was not appropriate, he insisted that the Doctor bluff his way out with a jelly baby instead.

In the United States, jelly babies had a low profile as a confectionery product. When Pinnacle Books published Doctor Who novelisations in new packaging, the editorial changes made by them included changing jelly babies to jelly beans, for fear of confusing American readers. Later, when the series had a great deal more popularity, many Americans simply associated jelly babies with Doctor Who and with the Doctor as played by Tom Baker. Under license from the BBC, one company sold jelly babies in packaging resembling the Doctor's TARDIS, advertising them as "the Cosmic Candy of the Time Lords".

The Inside the TARDIS featurette on the UK DVD of the tele-movie Doctor Who includes a closeup view of the bowl of jelly babies enjoyed by the Seventh Doctor at the start of the movie.

Jelly babies appear as collectible cards in The Adventure Games.
