Garth and Bev - Ballpoint Pen

Animation about a time-travelling brother and sister called Garth and Bev, who live in harmony with nature in their village. They are transported to different times and places by the Time Spiral and solve problems with the help of Grandfather Lir. It's the day of the Great Ballybeg Race and Lir says Garth and Bev can compete this year. Trouble is, the flags they've used to mark the route keep going astray and pretty soon, everyone is completely lost! Later, Grandfather Lir sends them to visit Laszlo Biro in Budapest to see his invention, the Ballpoint Pen.
