This link contains all the Jolly Roger Soundbites in the phase files at this time. Many are just generic and for the PR invasions, but there are also more than a few talking about Tortuga and Padres Invasions, with the main target of the Tortuga invasions being the Faithful Bride (and Jack Sparrow). The target of the invasions on PDF is very unclear though, as it isn't mentioned.
A few in particular that point out Tort and PDF invasions:
Tortuga:
Padres Del Fuego:
Also, just a note: Just because these files appeared do not confirm Padres and Tortuga invasions. As always these could just show up in the files and never be used, as the kraken, sea monsters, and Davy Jones did. I would think that these were placed in the files simply because the Disney team wanted to save time and considered the possibility of having invasions on other islands, so they had the soundbites recorded for them just in case.
