Walter the Worm (Dr. Sixth)

An equivalent of Earth's Walter the Worm existed on the Blue Planet. As with everything else on the planet, he appeared similar to his Earth equivalent, but blue. He seemed to be indifferent about sitting in holes and was also slightly longer than his Earth counterpart. When the Sixth Doctor and Peri Brown were exploring the planet, he was happily slithering along on the ground next to them for some of their walk. (PROSE: Dr. Sixth)
