Part VI: Guybrush Kicks Butt Once Again
Finish Him!!
Hop out of the Roller Coaster in the 1st screen. Grab the rope, then hop into the next available car. On the 2nd section, jump out and grab the Keg o' Rum. Once you get to the 3rd screen, open the Lantern. Blow out the candle and grab the Flask of Oil. Screen 4 has a Giant Snow Monkey. Walk up the hill thing and go to the monkey arm.
Use the Keg o' Rum with the Arm. Now use the Flask of Oil with the Rope, and use the oiled rope with the rum barrel. Head to the bottom and wait. After a bit, LeChuck will appear. Use the Pepper Mill with him, and watch the ending!
