Is there any frog in Japanese? I think so. Maybe that’s why these frog know about Kamikaze. They willing to die in order to kill you. Prepare your gun and shoot them. Your shotgun have only 10 ammo. Reload it with pressing your spacebar button. Like another frog, this stupid frog also jumping. And it make you difficult to shoot them. Every one frog hit you, you’ll lose 10% of your life. Ten frog and you’ll die.
