When some of the hermangrass seeds fell into tunnels, they adapted by being more sensitive to sunlight and became hugograss. They also adapted to be smaller in order to fit more of their species into the tunnels. Hugograss has evolved a thick skin and became smaller, which allowed them to store more water. However, they still reproduce the same way its ancestor did. The hugograss still forms small beads in the tips of its leaves when they touch the ground and create roots to form new plants that remain joined to the mother-plant.
