A Czech cartoon from the 60s and 70s called 'The Mole' was shown here in Australia. Most of the episodes ranged from 6-10 minutes (others, though were much longer) and were typically shown as a filler between other cartoons as I recall. "The Mole" was very popular in Czechoslovakia and is national icon these days. There was no narration and simple storylines. I always loved the style of the animation as a kid and vividly remember one epsiode where the gardener was trying to poison the mole because the mole kept digging holes in the lawn.
