After fronting TV3 children's programmes Early Bird Show, 3pm and You and Me, Suzy Cato started her own company, Treehut Productions, to make Suzy's World. A science show for five to nine year olds, it sought to explain everyday phenomena like how smoke alarms work, why birds sing and where salt comes from. With the accent very much on the practical, pantyhose played an important part in simulating the workings of the digestive system while a watermelon was hurt demonstrating inertia and the need for seatbelts. Over four years 263 episodes were made.
