In "Parks and Recreation", what is the name of Jean-Ralphio Saperstein's greedy twin sister?

In “Parks and Recreation,” Jean-Ralphio Saperstein’s greedy twin sister is named Mona-Lisa Saperstein. She is portrayed by Jenny Slate as an aggressively self-centered, reckless, and chaotic character whose behavior matches the Saperstein family’s flamboyant reputation.

Mona-Lisa first appears in the season-five episode “Bailout,” when Tom Haverford hires her at Rent-A-Swag. She soon becomes Tom’s romantic partner as well as a major source of trouble for the business. Her impulsiveness and dishonesty help create problems that eventually contribute to the store’s decline.

Jean-Ralphio describes Mona-Lisa as “a klepto, and a nympho, and a pyro,” a comic summary of her theft, sexual recklessness, and apparent fascination with fire. The siblings are presented as equally irresponsible, although Mona-Lisa is often treated as the more dangerous of the two.

The hyphen and capitalization matter for the canonical character name: it is Mona-Lisa Saperstein, not simply Mona Saperstein or Lisa Saperstein. She is the daughter of Dr. Saperstein and appears across seasons five, six, and seven, including the series finale.
