Guybrush meets Estevan (Special Edition)
Estevan was a pirate met by Guybrush Threepwood in the Scumm Bar while searching for the Pirate Leaders.
He had a scarred eye caused when putting in his contact lenses.
He was the local expert on LeChuck and took the subject extremely seriously, quickly getting shaken up by talking about him.
He mentioned that people often steal grog from the kitchen, which may have prompted Threepwood to do the same.
Behind the scenes[]
In the EGA demo mini-game he is known as One-eyed Frank, and referred to as a pirate leader.
