Root Beer is a beverage made from a plant which can be found growing on Monkey Island.
It is also known among Voodoo Practitioners to be a powerful weapon used to destroy ghosts.
Secret of Monkey IslandEdit
LeChuck knocked the mixture out of his hands and only by chance Threepwood found another bottle of Root Beer from the Grog Machine at Stan's Used Ship Emporium, which he shook up and sprayed at the ghost pirate. LeChucks spirit form was destroyed in a display that looked like fireworks.
Monkey Island 2Edit
LeChuck was ressurected in his rotting corpse and once more a confrontation between and Threepwood took place.
Threepwood found some Root Beer from another Grog Machine under Dinky Island and attempted to use it in the same way he had a year before, but found that it was inneffective, as LeChuck was not a ghost any more.
Tales of Monkey IslandEdit
A flat bottle was found kept inside the Monkey Casket of Kauai. Threepwood needed it in order to complete the creation of his Cursed Cutlass of Kaflu. First he had to make the beer fizzy again. He did so by adding a Breath Mint.
