Break the Blockade

All of our ships are sunk! We need your help to break the pirate blockade below in the Shattered Straits!$B$BTake these cluster bombs and hitch a ride on the zeppelin that Harrowmeiser has 'loaned' to us. He'll fly you over the decks of those pirate scoundrels, and you make sure to give it to them good!$B$BIf you can't bomb them to smithereens, I'm afraid we'll never be able to break the blockade.
