Rosalita is a Spanish-speaking maid that was hired to help pack as Mrs. Walsh's arm was in a sling.

Because Rosalita speaks only Spanish, Mrs. Walsh needs Mouth to translate her instructions. When speaking to her Mouth instead describes the Walsh home as having a roach infestation, illegal drugs, and sexual torture devices, and that poor service would result in her being locked in a closet without food or water.

Later Rosalita finds the precious gemstones in Mikey's marble bag that save the Goon Docks from being turned into a golf course.
