Double click the flag to start Aerther's Ally, the Clown King, are after you for taking out Aerther. Press space to throw a book at your enemy. Press down to throw a pokeball that will catch the minions. Don't get touched by a clown. After about 30 seconds the Clown King will appear and you have to fight him. Watch out for His Boom Balloons, they explode on contact. Use the arrow keys to move left and right. I recommend that you use a mouse.
