Stugg was a young inquisitive otter and the son of Abruc and Marinu. He often asked his father different questions. Others (particularly Lonna Bowstripe) constantly referred to him as having the potential to grow into a great warrior. He and his father found Lonna wounded in the scrub forest while they were wandering on the coast near their holt. Stugg went to get the others for help. Later he became a friend of Lonna, and was mentioned as a good cook.
