You can do this on easy so you have plenty of money. I used winter park so i had water for Sub & buccaneer. You must surround your super money will EVERY TOWER IN ONE GO. Didnt pop for me splitting the towers.
Once your super money is at 3-2-0 , upgrade to 4-2-0 and it will pop once the game is over.
