When he came down, Roar was sleeping and basking in the sun. If he didn't have fur, Arthur would think he was sunbathing. But with fur, Arthur was sure that he was basically absorbing the sun.
Roar's fur is golden and shiny normally. But when exposed to a lot of sun, his fur shines like metal, specifically like gold. His fur also glows.
The way his fur behaves under sunlight is why Arthur believes that Roar is executing a scheme in which he slowly absorbs the power of the sun until one day he swallows the sun completely and replaces it as the source of light and life for the Ethera world.
Roar's eyes moved as he picked up the sounds of Arthur's movements. But he didn't stand up from his sleeping posture.
Instead he yawned and flipped over, thereby exposing his belly to Arthur. Then one of his eyes stared at Arthur with meaning.
Arthur shook his head at the sight and said, "Look at how lazy you've become. You even want belly rubs without asking for them."
