Old Brown is the main antagonist in Beatrix Potter's "The Tale of Squirrel Nutkin". Squirrel Nutkin, his brother Twinkleberry, and their many cousins sail to Owl Island on little rafts they have constructed of twigs. They offer resident owl Old Brown a gift and ask his permission to do their nut-collecting on his island. Nutkin however dances about impertinently singing a silly riddle. Old Brown pays no attention to Nutkin, but permits the squirrels to go about their work. Every day for six days, the squirrels offer gifts to Old Brown, and every day as well, Nutkin taunts the owl with another sing-song riddle. Eventually, Nutkin annoys Old Brown once too often. The owl seizes Nutkin and tries to skin him alive. Nutkin escapes, but not without losing most of his tail. After this he becomes furious when he is asked riddles.
