The Wombles has a few fantasy elements:
A main character from a made up race.
A setting that is basically invented. Wimbledon Common is nothing like the setting in the Wombles.
As such would it be on topic?
Based on the description on Wikipedia, there are a considerable number of canon elements that would put the show firmly on-topic on SFF:SE, notably that a number of supposedly fictional animals (Yetis and Nessies) are in fact womble sub-species as well as the presence of magic and telepathy.
Several sub-species of Womble are revealed throughout the books: the Loch Ness Monster is actually part of a clan of water Wombles and the yeti of the Himalayas are giant snow-white Wombles. Wombles have a sixth sense which allows them to sense green spaces and wildlife; this is first mentioned in the Wandering Wombles but developed to a keen long range telepathic sense by Dalai Gartok Womble in 'The Wombles Go Round The World'.
