Arroyo is a pale, sandy color with tan underscales and black eyes. He is large, and has a bite mark on his tail and several small scars on his snout.
He is seen returning from a hunt with his son, Courser. He greets his wife, Nyala, and his daughter, Loess, then criticizes Courser's catch. He eats it with his family for dinner. In the morning, Loess awakens him when SandWing soldiers arrive. He fights, but they take him prisoner with Courser.
- An arroyo is a small, steep-sided gulch, usually dry except for after heavy rains, often in deserts.
