Betty Balloon tells the story of a modern family - who just happen to be balloons. Mom Balloon is an inventor, Dad Balloon runs the home, Bobby Balloon is a super tweenie, and the heart of it all is Betty Balloon, a creative and imaginative four-year-old. Life turns upside down when a cactus family moves in next door. Mom Cactus, Dad Cactus, tweenie sister Karla Cactus and four-year-old Kaj Cactus. The Balloon family must learn to connect with their new neighbours, but it is the children who take the first step when Betty Balloon becomes best friends with Kaj Cactus. In the Betty Balloon universe, it is the kids who teach the adults how to open and stay curious.
