This season is comprised of ten episodes focusing on multiplication. Each episode opens and ends with the episode's table being chanted, and the Joker (played by Jenny Hutchinson) introduced it in rhyme while speaking directly to the audience (she would also welcome teams of schoolchildren who came to visit the castle and give them advice as they took part in mathematical challenges). The two gargoyles, Gar (male) and Goyle (female), also made observations on the mathematical happenings in the castle then summarized what its residents learned near the end of each episode (the week's table would also be displayed on the portcullis as it lowered), and the castle pets, Brimstone the dragon and Digit the kitten (who were drawn by Bevanfield Films in this series), had their own adventures below stairs in the cellar. This series was originally aired on Mondays as part of the BBC's schools programmes strand, then entitled Daytime on Two, at 9:40am.
