In this game you need to give the spines to the cactuars, durians, hedgehogs, porcupine fish, and sea urchins. You do that by shooting the spines at them so that the spines stick to them. Your target will be rotating so that you can put spines in different positions. Beware, you must not shoot a spine at a place where there is already one, otherwise the game will be over. After putting a set number of spines, you can advance to the next level. As you reach higher levels, you will need to put more spines and your target will be rotating faster, making it more difficult to put in spines at the right place. The higher the level you have reached, the higher your rank.
