"You can still crawl," he points out.
Rincewind looks on enviously, wishing he had a cup of tea. Oh well. Maybe this time will work. He's still holding on to his white stone. Carefully, carefully, he navigates the yellow line, arms windmilling as he tries to keep his balance. Good, good, don't look around, just watch your feet...better, almost there. And done! Rincewind sags with relief.
