Larry Koopa - the final boss of the 1st world. He jumps, shoots homing fireballs and magic projectiles that fly towards you, jumps in his shell, throws many small fireballs and swing with his wand-sword. You can just jump on him to defeat, but it would be better to have power ups, because he is not easy at all. You should use many moves to avoid his attacks. In his second phase he uses all power of the Dark Star in his wand and transforms (look at this by yourself). After defeat he drops the dark star. You should clean it with the Eternal Star pedestal that you can find in the castle. After this find the painting of the desert world and unlock it with the power star! But now there is no desert world, I'll add it in the future.
