She is portrayed by Lydia Boland.
In The Quad-Test, Dicky asked Molly out and showering with his security item, the duck. In Quad Court, Molly and Mae have a fight because Molly had given Mae her shirt but Mae had dropped dye on it. Mae denies it but the Quad Court finds her guilty and she offers to wash it for Molly. During the trial, Dicky tries several times to "sentence" Molly to go out with her and she's interested.
Because Molly's frequent fights with Mae, Dawn predicts that Molly and Mae would be the epic moment during the museum class trip in Nicky, Ricky, Dicky & Sicky. Molly and Mae start fighting as expected but their fight turns into a shared admiration for cats since they both love cats so much.
In Odd Quad Out, Molly and Mae praise the Kramden Quads saying they're more of real quadruplets than Dawn, Nicky, Ricky and Dicky. This makes the Harper Quads even more insecure, feeling more threatened by the Kramdens.
In Lasties with Firsties, Molly's going on a skydiving date with Ricky and crash into the quads' house.
