Boardlilly

To prevent the parasitism of the crystal root, the sailily modified its circular base to a structure in board form, which speeds up its movement in the water. Because they are faster now, the crystal root has more difficulty arresting on it and, in case it does happen, it has more possibilities to free itself. For the sail to resist more tension provoked by the wind, a small "rope" formed from the pole and helps it to keep the sail firm.
