"Addanc aka adanc"
|Welsh||Addane, afanc, avanc, abhac, abac, a lake monster that also appears in Celtic and British folklore. It is described alternately as resembling a crocodile, beaver or dwarf, and is sometimes said to be a demon. The lake in which it dwells also varies; it is variously said to live in Llyn Llion, Llyn Barfog, near Brynberian Bridge or in Llyn yr Afanc, a lake in Betws-y-Coed that was named after the creature.
