Garth and Bev - Hook and Loop

Animation about a time-travelling brother and sister called Garth and Bev, who live in harmony with nature in their village long ago. They are transported to different times and places by the Time Spiral and solve problems with the help of Grandfather Lir. Garth and Bev collect seeds for Grandfather Lir after Niall the Sheep ate all the ones in his garden. But Niall turns out to be a great help because they find that certain seeds stick to his wool and they can collect loads! Through the Time Spiral they discover that's a lot like how George de Mestral got the idea for his sticky clothing fastener.
