okay, the pirates of this island have gone thru all sorts of changes over the centuries. the grownups on the island are ashamed of their pirate ancestry, and allowed a theme park to be developed. now they rake in money from the tourists in sort of piracy, and drink alot.
the kids of the island reject all the sellouts of their parents. they have pirate fever, and all their acts of rebellion take this form. they rob the ticket booth, for example.
they have taken the old stories seriously, and think they know where the gold from a shipwreck lies. they arrange to recover it and hide it from the authorities, which is piracy.
their parents know what’s going on, and exploit the situation.
