Kraken

The Kraken is a monstrous creature resembling that of a titanic squid, over 1,000 feet in length. It once served Davy Jones, who uses it to destroy his enemies. If a sailor had Jones' notorious black spot upon him, the Kraken would pursue that man to ends of the Earth - and pray he not get too close to open water.

This beastie attacks with massive one-hundred foot long tenticles that can sweep a man out to sea, to either drown or become a meal.

Though it was reported that the kraken's corpse was discovered on a beach of a place known as Kraken Island {POTC3). But, rumors say that it stalks the waters off Isla Perdida.

''Game Note - There have been a screenshots of Kraken tentacles attacking ships, but as of yet - it has not appeared in the game. But, if it does - the mention of using Grape Shot cannon rounds against 'sea creatures' may indicate that all hope is not lost if attacked.''
