One of the successes of children's television strand The Den was its ability to continually produce an array of successful characters, many of whom then went on to achieve fame in other fields, both nationally and internationally.
Generation I include extraterrestrials Zig and Zag and their dog Zuppy, all of whom were present from the second season of Dempsey's Den. Zig and Zag left in 1993 but Zuppy remained to become one of the longest serving members of The Den team (alongside Don Conroy, a human).
Zig and Zag, the first (and possibly the most famous), are ten-year-old alien twins from the planet Zog. They were a very successful franchise on their own, spawning parody tapes, comic books and car toys. A popular toy throughout the late 1980s were zogabongs, the unusual antennae on both Zig's and Zag's heads.
Zig and Zag arrived from the Planet Zog hoping to collect jokes. They were adopted by the young television presenter, Ian Dempsey, and became regular features on Dempsey's Den whilst living at Number Ten Celebrity Square (it has since been demolished and now has a Lidl on it). At first they would appear separately on designated days of the week and once a week together, then their appearances became more frequent. Zag was responsible for introducing Dustin to celebrity acclaim when he won him in a golf game, however both he and Zig had a difficult relationship with the turkey. An offer arrived from Channel 4 and the two extraterrestrials left The Den in the summer of 1993.
Zig and Zag received a presenting job on Channel 4's The Big Breakfast, whereas Zuppy, Soky and Dustin remained. Zig and Zag returned to Ireland in the late 1990s to host 2Phat, a music-quiz show along with their father, Ray D'Arcy, in which students had the chance to win a limited edition scooter. The show ran for two seasons and was well received. Other popular characters on the show were Velcro Girl, DJ Lee, Zag's alter ego Reverend Groove and Zag's alter ego Captain Pillowcase. After a period of disappearance, they returned to launch a multi-layered assault on the media in October/November 2008, first featuring on their own television special, Best Bitz From Back Den and later appearing on the prime-time chat show, Twiggery Tonight, and their old father's radio show, The Ray D'Arcy Show, to promote its release as a DVD.
