Marina Prattle is a pre-made playable Sim residing in Bridgeport, the world shipped with The Sims 3: Late Night. She lives in a penthouse in the urban area with three roommates, Bianca Rubble, Lilly-Bo Chique, and newcomer Beau Merrick. According to her biography, the three girls had been best friends until Beau moved in. The three girls have, since then, become romantically involved with him, which has apparently cost them their friendship.
Marina shares her surname with Seraphina Prattle, a paper delivery girl from the same neighborhood. Seraphina also has identical hair, eye color, and facial features to Marina. However, they are not listed as relatives and do not know each other when the game starts. Whether the two were meant to be related in any way is unknown.
Since Marina has blonde hair with slightly darker roots, it is possible she may have dyed it.
In German, her name is Vicky Prattle. In her biography, however, her name is mistakenly written as Marina.
She is the only one of Beau's lovers not to have a sibling.
She starts off the game with poor job performance.
