Oh my word!! I can see them now.

Making a human bridge across 26 miles of the English Channel. Swarming into and over Kent.

Spreading their tentacles past vast swathes of the Home Counties. Heading was to Hampshire, Dorset, Devon, Somerset and Cornwall. Eastwards to Essex, Norfolk, Suffolk, Cambridgeshire and eventually HERTFORDSHIRE !!! Heaven forfend.

Entering London.

Making inroads to the North as far as Durham, Cumbria and Northumberland.

It's about time someone wrote a fairy story about it, What!? They already have.

Oh bugger.
