Roro are a species of creatures who like to live in tall towers. They are native to Jeem, and have a tendancy to steal building materials, like bricks, metal bars and bags of cement. Using their collected materials, they make a tower ten or more metres tall, covering it in cement to hold it together. They then make a small hut on top of the tower, where they sit and yell 'rorororororororo'. the only time they leave their tower is to find food, or rebuild their tower.
