There are some weird UK cryptids. Will-o-the-wisp, Barghest, Redcaps,Boggarts Gryndylows The Lambton Worm, nessie, kelpies and on and on and on. Granted I and manyothers doubt the existence of most of these beings living in our dinky Island with more houses than shrubs but the one about the Lambton Worm may have some truth in it ( at least the first part) where it’s described as with nine holes on each side of its Salamander-like head which screams lamprey although I can’t vouch for a giant draconic creature that eats sheep and attacks people.
The Beast Of Bodmin Moore on the other hand ( or paw) is one which many people debate to this day and I personally think that big cats in the UK is a slight possibility although many will strongly disagree with me. If someone ever does spot a big cat in the UK and upload it to Inat then that would be something.
