Trivia

 * The cooldown time for the whirlpool ability is 55 seconds.
 * This is one of the very few water tiles that Ninja Monkeys and Bomb Shooters can be used on, the other being Submarine Alliance.
 * There is an error in the whirlpool, when selected in BMC Flash, it will read 'Whirpool' instead of 'Whirlpool'.
 * Interestingly, the Monkey Sub is also doubled in price. One logical way of explaining this is that boats such as those Buccaneers use are easier forms of travel to the shipwreck site than does non-boat forms of transport, including submarines.
 * The mission can be completed without using the whirlpool ability, but it is very difficult to achieve.
