45% of the voiced dialogue this expansion for the EN version was from a dude pretending to be a woman, pretending to be from South America when they're a jew from the Midwest and doing the 1/64th cherokee meme but Puerto Rican, with negative acting talents and barely any experience, for a character that quite literally is a combination of Poochie from the Simpsons that also steals the credit / valor from every member of the crew you go with in the expansion.
