From 22 September to 1 December 1998, the BBC broadcast a "revised" version of this series as a lead-in to the sixth series; in place of Lolita, Bill (introduced in the fourth series) and Bernie (who joined him in the fifth one) introduced each episode with a number line of their own (however, Lolita's voice was still heard narrating some re-used animated sketches). All except seven of the original live-action sketches were replaced with the Dolls' House (again, see Series 5) ones - and the "El Nombre" sketches were slightly lengthened. Sequences of children discussing the ten numbers (in the vein of those discussing the time-related concepts covered by the fifth series) were also introduced; although the "Planet of the Eights" sketch was also re-used, the vocal track was redubbed and Lolita was edited out of it.
