The Beast of Bowness is a cryptid only seen in "The Secret Saturdays: Beasts of the 5th Sun". The Beast of Bowness, also known as tizzie-wizzie, is a small, winged, hedgehog-like creature with a squirrel's tail.
Sightings of the cryptid are fairly rare, but are said to unlock mysteries for those that find them. Doyle used them to escape from Weird World. They are mostly found in Windemere lake, Texas.
