A local creel fisherman Lorn MacRae spotted the walrus hauled out on a rocky outcrop called Cairn Na Burgh Beag - a small island which forms part of the Trenish Isles, off the coast of the Isle of Mull.
Thor was found lounging on a floating dock by Ellis Elisson, 41, who was supervising one of his fishing boats at a harbour in the small Icelandic fishing town on Friday morning.
