Pentagalloon

The pentagalloon replaced its ancestor, the balgalloon. Not only has it increased in size, it has gained some replaceable, auxiliary rings on the outside of the main ring. This allows it to flow with the river water even better, and it increases its surface area, allowing for better use of sunlight. In difficult times, the auxiliary rings will break off, and get swept away by the rivers current. The smaller ones will grow larger and eventually small twists form at equal intervals around the ring, commonly four. These then grow into the auxiliary rings. For the large one after the break up, it will do the same.
