Kraken and Davy Jones?

[Angel Seafish]

Ok, so one of my friends told me that before the invasions (at the 30 minute warning) the Kraken would come out and you could fight it. I'm not sure if I believe it though because no one else has reported it.

Another friend of mine said that if you sailed to the end of the world you could fight Davy Jones and he was the ??? like Jolly Roger, not at a specific time. Again I am not sure because I have not heard any other reports of this.
