Tob is Lucy-May's two-year-old brother, the youngest member of the Popple family. He journeys with his parents and siblings as they relocate from England to pioneer South Australia in the 1830s, experiencing the hardships and adaptations of frontier life alongside them. His presence factors into minor plot points illustrating the family's daily struggles, such as plunging into a pit while pursuing an orphaned kangaroo with his sister Kate, requiring her rescue. This highlights his inherent vulnerability and reliance on older relatives. Across the series' fifty episodes, Tob's role remains consistently focused as the family's youngest child, enduring their collective challenges including his father's financial difficulties and their eventual resolution. The narrative confines his depiction to this familial context, without expanding on personal growth through exclusive arcs. His portrayal is limited solely to the original television series.
