The ninth (and final) series, which is aimed at six- to seven-year-olds, comprised ten episodes focusing on the concepts of adding and subtracting similar to the fourth series (only without Lolita, live-action sketches based on nursery rhymes, or Test the Toad); in this series, Numbertime News, which had appeared in five episodes of the first series with Sammy Sport (played by Andy McEwan, who had played Matt Dillon in "Death Without Dishonour", the twenty-sixth episode of "Taggart"), along with one episode of the fourth series with Rebecca Testament (played by Issy Van Randwyck), became a recurring sketch, with anchorwoman Tara Boomdeay (played by Elisabeth Sladen, who had played Sarah-Jane on "Doctor Who", as well as several characters in fifteen episodes over the third and aforementioned fourth series) and roving reporter Brad Quiff (played by Ian Connaughton). This series also saw Michael Fenton-Stevens returning to join the "El Nombre" cast and introduced the character of Addem (voiced by Richard Pearce), a green snake who discovered the series' concept in the company of a yellow ant named Ann (voiced by Moir Leslie) and a whole civilisation of other multi-coloured ants (mostly voiced by both Brian Bowles and Richard Pearce, but the Queen Ant was again voiced by Moir Leslie).
