Teggie is a mysterious group of lake monsters living in Bala Lake, Wales. It is not related to the Loch Ness monster though. It lives in a colony which are able to survive the cold temperature of Wales.
There are rumours that a group of seals was trained in World War one attack warships.
Their training included to have them tied up with dynamite and send them against enemy boats. This project was just a test and it was soon abandoned. The seals were then left there to survive on their own.
Teggie is said to resemble a large pike. It is as long as three dogs swimming together, and has humps that poke through the water.
