Another wave of vicious beasts is coming, and the young lords of Heisha are worried that the light of the city will not be able to withstand the multiple attacks of the beast. They decide that they have to kill the nearest beast first, and then they can use their power to destroy the beast's armor. They think that the black energy from the Ape can corrode the armor, and so they decide to use the power of the purple vines to bind the beast up, so that it will be unable to attack again.
