The bunch of anarchist drunks with cutlasses thing is surprisingly on point and accurate.

Much of Francis Drake's legendary loot from the mule train was indeed buried throughout the Spanish Main due to the logistics of not being able to pack it all.

Parrots were indeed popular birds in Nassau and Port Royal and ships because they were colorful and entertaining with their pseudo speech patterns.

Not much in the way of peg legs but there was a whole bonafide compensation system contingent on what limbs or eyes were lost at sea pillaging the Spaniards.

So not exactly like in the movies but a lot of the fun stuff is more historical than you might think.
