Stunned zoo staff sent a team to investigate after a crocodile was spotted in the mongoose enclosure -- which turned out to be a TOY.
Officials at Folly Farm Adventure Park and Zoo in Pembrokeshire, Wales were alarmed when the mysterious creature was seen by a guest.
But on closer inspection from the team it turned out to be a toy crocodile someone had dropped in by accident.
Folly Farm posted on their social media: "This mysterious 'creature’ was spotted by one of our guests over the weekend in the banded mongoose enclosure and had us all scratching our heads… Was it a miniature Loch Ness Monster? A mysterious water lizard?!
"We sent our zoo team to investigate and I can reassure you all that it was just a toy crocodile that someone has dropped into the pond!
"We breathed a little sigh of relief I can tell you - but it did give us all a laugh this grey Monday morning!"
