|Nothing is too good for Gwennie. She loves shelling out huge amounts of simoleons on designer clothes that look like she's been dragged through a junk yard.|

Gwennie Peach is a repairwoman who's working in Barnacle Bay. She has 5 points in writing and, oddly, no handiness skill, considering that she needs it for her job. She is said to buy expensive clothes, but her sloppiness makes Gwennie look like she was dragged through a junkyard. Gwennie can be made playable by asking her to move, in or by marrying her. Her counterpart is Mario DaCosta. The two of them are genetically very similar, but unrelated.
Unusually, there are two repairwomen instead of one of each gender, and it is heavily implied that Mario was actually meant to be male, with a male name and referred to as "he" in her bio. The fact that she is female may have been an oversight or a last-minute change to her character without fixing her bio.
Additionally, they appear 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. Despite this, neither of them resemble the characters they reference.
