Well, I find that the option that Blackbeard spared the crew's life is very unlikely. Although Murtogg, Marty and Mullroy are shown alive in Pirates of the Caribbean: Dead Men Tell No Tales, I suppose that they might have survived Blackbeard's attack, but there's the possibility that they could have resigned from Hector Barbossa's crew by that time, as in the case of Gillette and Theodore Groves, who could have resigned from James Norrington's crew by that time. As with Cotton's Parrot, I was the one who put the theory that he could have died of starvation with Jack the Monkey surviving that Fate for his immortality at that time. However, as others think, he could have remained below deck, flown away offscreen or just Jack Sparrow simply allowed him to fly out after taking out the cork at some unspecified point.

And for Pintel and Ragetti, I'm sure that they could have survived because there were plans to originally use them in both Pirates of the Caribbean: On Stranger Tides and in Pirates of the Caribbean: Dead Men Tell No Tales (search their concept arts as Barbossa's rich and wealthy crewmen in their respective gallery pages). And for Cotton, who cares about him.

However, I had another possibility: Many of the crew were shrunken along the Black Pearl. Over the time, they consumed all the food and they eventually starved to death. Cotton's Parrot ate their bones and flesh, but eventually, Cotton's Parrot passed away for starvation, while Jakc the Monkey survived because he was undead.

The End! :)
