Measure
The fourth series, which was produced in 1998 (and the last to be set at the castle on Table Mountain), comprised five episodes focusing on units of measurement. Brimstone and Digit also underwent a second redesign for their final series by second new animators Blue Sunflower Animation, but their appearance was only slightly different to how they had appeared for the second and third series.
