Back in the day, a pirate would plunder a town and rob it of its booty (treasure in laymen terms). They would then take their booty to a remote location, usually a deserted island, and bury it till the coast is clear. They would make some kind of a crude map so they could find later after the heat died down.
What happens when the map is lost you ask? Good question! We're about to find out in this episode of The Further Adventures of the Brownfrowns, Booty. The Captain looses his booty, and the laughs roll on.
