Cuthbert Goes Walkabout is based on the arcade game Amidar. Basically, you have to circle the squares to fill them in with a color, and do so for the whole maze, while dodging creatures. There are also bonus levels after you complete screens.
Like Cuthbert Goes Digging, this was a game originally done for the Dragon 32/64 market in England, before being ported to the Coco.
