Back to the Future Part III: Timeline of Monkey Island

Marty finally gets the almanac, leaving Biff to crash into a manure truck. Marty burns the almanac, reversing Biff's changes to the timeline, as Doc hovers above in the time machine. Before Marty can join him in the time machine, the DeLorean is struck by lightning and disappears. The Voodoo Lady through a voodoo magic explains to Marty the timeline has changed. Doc was transported back to 1655. Marty races back into town to find the 1955 Doc, who had just helped the original Marty return to 1985. Shocked by Marty's sudden reappearance, Doc faints. Great Scott!!!!!
