Mario DaCosta

Mario DaCosta is a pre-made repairwoman who is working in Barnacle Bay. She has 2 skill points in Fishing and 5 in Guitar. It is notable that Mario is a Portuguese/Spanish name used for males. Her counterpart is Gwennie Peach. The two of them are genetically very similar, but unrelated.

She probably was intended to be a male Sim, as her bio refers to her as a "he", she has a traditionally male name and worlds in The Sims 3 often have one male and one female of each NPC instead of two females. The fact that she is female may have been an oversight or a last-minute change to her character without fixing her bio.

Her name combined with Gwennie's last name indicate that they are meant to be a reference to Mario and Princess Peach from the Super Mario Bros. franchise, including the fact that Mario in that series is a plumber, and Peach, being a princess, wears expensive clothing as Gwennie is stated to do. Her bio mentioning "mechanical surgery" and the joke about wearing a stethoscope may be a reference to the Dr. Mario spin-off series of Mario games, which feature the plumber as a doctor. Despite this, neither of them resemble the characters they reference. Additionally, she appears to have Spanish heritage (as evident by her name and interests) even though the other Mario is Italian.
