The sixth series (which is, again, aimed at five- to six-year-olds) comprised five episodes focusing on the numbers 11, 12, 15, 17 and 20. Each episode would open with Bill and Bernie finding the position of the episode's number on their number line (which had been carried over from the "revised" version of the first series that was produced in 1998) - and in this series, Santo Flamingo gained an ice-cream seller named Señor Gelato, a carpenter named Señor Chipito (who had, once again, previously appeared in the second series as the owner of "The Maggot and Cactus" saloon) and a bandit named Don Fandango (who stole twenty gold coins from its newly built bank, which was managed by Señor Calculo, in the last episode). This series also saw former "Blue Peter" host Janet Ellis joining the "El Nombre" cast; although this series was made in Winter 1998, it was not broadcast until 12 January 1999.
