Legend (click on game screen to begin, use arrow keys to navigate) You: Guybrush Threepwood You are a swashbuckling pirate with a sharp sword and an even sharper wit. You also have a strange affinity to monkeys. The Ghost Pirate LeChuck LeChuck is your sworn enemy, even though you have killed him 4 times, and he was already a ghost before you met him! Don't get too close or he'll follow you. If he makes you too uncomfortable, insult him (space bar) and he'll back off. Largo LaGrande Largo is just a bully. But he's a bully that just happens to be the spitting champion of Booty Island! Get too close and he might show off his talent! Stan...just Stan Stan is a salesman. A particularly relentless and annoying salesman. If you get within earshot he'll start following you around spouting deals and selling previously-owned merchandise. Word on the street is although humans are annoyed by him, the monkeys think he's a tasty treat! Three-Headed Monkey AAAAGHH! A THREE-HEADED MONKEY!!!
