As you may have gathered, we have a Wildlife Park here, and some wallabies escaped many years ago. The area is the Ballaugh Currachs, a damp and flat area. Untill 60 or so years ago, it was "farmed", but allowed to go to pot. (No, not that sort!) Willow trees quickly invaded the whole area, which all makes good cover for the Wallabies. Apparently in the breeding season, they queue up by the fence hoping to share something. Until that same 60 or so years ago, the island was populated, infested maybe, by "little people", and stories still do the rounds. There is the church whose roof was blown off, every time it was rebuilt. Can't remember which fairy did that, but all the true manxies know.
If you like a good fairy tale, a book was written a few short years ago entitled "Fynodderee". Don'y know if downloadable, but a good read.
Back to Wallabies. I hail from Staffordshire, and it is well known that one "Sir Phillip Brocklehurst" had some wallabies which escaped and became feral on the Staffordshire Moorlands where they could be seen for many years. However, I am told they have now died out due to inbreeding.
