The Quintuplets are a Romanian set of contorting sisters. They perform at the Cirque Du Cheville in the Season Four episode, "Quintuplets 2000". Only four of them have names: Glacas, Nadia, Natalia, and Baltania. The name of the fifth sister is never given.
Being identical quintuplets, they all look exactly the same. They wear the same clothes as well, a light blue shirt with a large, white trim, and a blue skirt. They have what appears to be a white bow in their abnormally wide, black hair.
In "Quintuplets 2000", the boys attempted to befriend them so they could use them in their own "circus". They tried to show the Quintuplets about what is great about America, so they would stay. It is very likely that they broke off their friendship with the boys, stating that the boys were "the worst of them all".
They despise their father, who neglected them when they were younger because he walked out on them five years earlier.
After their mother died, their grandmother became their caregiver, it is presumed they had a close relationship before she died.
